Optical disc offers 500GB storage
A disc that can store 500 gigabytes (GB) of data, equivalent to 100 DVDs, has been unveiled by General Electric.
The micro-holographic disc, which is the same size as existing DVD discs, is aimed at the archive industry.
But the company believes it can eventually be used in the consumer market place and home players.
Blu-ray discs, which are used to store high definition movies and games, can currently hold between 25GB and 50GB.
Micro-holographic discs can store more data than DVDs or Blu-ray because they store information on the disc in three dimensions, rather than just pits on the surface of the disc
A single GE disc could be used to package up a library of high definition movies but is there pent-up consumer demand for such an offering?
News website Technology editor Darren Waters
Read more on the Dot.Life blog
The challenge for this area of technology has been to increase the reflectivity of the holograms that are stored on the discs so that players can be used to both read and write to the discs.
Brian Lawrence, who leads GE's Holographic Storage said on the GE Research blog: "Very recently, the team at GE has made dramatic improvements in the materials enabling significant increases in the amount of light that can be reflected by the holograms."
More capacity
The higher reflectivity that can be achieved, the more capacity for the disc. While the technology is still in the laboratory stage, GE believes it will take off because players can be built which are backwards compatible with existing DVD and Blu-ray technologies.
In a statement the firm said: "The hardware and formats are so similar to current optical storage technology that the micro-holographic players will enable consumers to play back their CDs, DVDs and Blu-ray discs."
''GE's breakthrough is a huge step toward bringing our next generation holographic storage technology to the everyday consumer,'' said Mr Lawrence in a statement.
He added: "The day when you can store your entire high definition movie collection on one disc and support high resolution formats like 3D television is closer than you think.''
Micro-holographic technology has been one of the leading areas of research for storage experts for decades. Discs are seen as a reliable and effective form of storage and are both consumer and retail friendly.
However, General Electric will need to work with hardware manufacturers if it is to bring the technology to the consumer market.
The relatively modest adoption of Blu-ray discs sales globally might be an issue with some companies who believe digital distribution and cloud computing is the long-term answer to content delivery and storage.
"This is truly a breakthrough in the development of the materials that are so critical to ultimately bringing holographic storage to the everyday consumer," said Mr Lawrence.

Seagate 'green' HDD saves power with slower spin
Barracuda claims top spot for economy hard disks.

Barracuda claims top spot for economy hard disks.
John E. Dunn, Techworld

Seagate has launched a ‘green' hard drive it says will allow system builders to slash disk power consumption without having to sacrifice performance.
The new SATA II Barracuda Low Power (LP) drive is physically identical to a standard 3.5 inch Barracuda desktop drive running at 7,200rpm, but special firmware slows the spin speed to a more economical 5,900rpm. Running more slowly reduces performance to some extent, but delivers less noise and less heat, which in turn allow system builders to use reduce the spec and cost on PC components such as fans and power supplies (PSUs).
However, the big pay-off is a reduction in drive power consumption of more than 40 percent. In an idle state the Barracuda LP uses 3 watts, or 5.6 watts while operating, which compares to the current Barracuda 7,200rpm's 5.0 watts in idle mode and 8.4 watts operating.
Seagate claims the drive also makes better trade-offs than rival ‘green' drive designs; Seagate figures showed Samsung's recently launched Eco Green using a whisker less power while operating - 5.5 watts to the Barracuda LP's 5.6 watts - but only at the cost of reducing spin speed and performance to 5,400rpm. Western Digital's Caviar Green used slightly more, 5.72 watts, although this is from a 5,400rpm design that first appeared almost two years ago.
The drive will be sold in capacities of 1.0TB, 1.5TB and 2.0TB, which means it will turn up initially in external USB and network-attached storage (NAS) drives, sectors that have become increasingly preoccupied with the issue of power consumption and heat dissipation. The benefits would be less pronounced for a desktop system in which the drive is only one component, but such drives clearly had a good future in the emerging niche of the low-power business PC, Seagate said.
"Growing demand for power-efficient computing systems is not just a data centre phenomenon as more builders of external storage devices, desktop PCs and home networking systems work to provide customers with products that combine power-efficiency with rock-solid performance," said Seagate vice president Joan Motsinger.
Seagate estimates that 95 percent of its 3.5 inch drive sales are for 7,200rpm drives, with higher-speed drives making up the remainder. The company would not be drawn on what sort of impression the arrival of the Barracuda LP might make on this market balance.
Pricing is $258 (approx £176) for the 2.0 terabyte model, with the 1.5 terabyte and 1.0 terabyte models costing $156 and $118 respectively.

Super Talent Announces RAIDDrive SSD with up to 2TB Capacity
Super Talent has announced its latest SSD development with a new patented product called RAIDDrive. RAIDDrive promises to increase the performance and slot capacity of PCI Express based storage solutions with up to 2TB of MLC or SLC NAND flash memory inside.
Super Talent says that the RAIDDrive is the markets largest server-based SSD solution and is an extension of its RAIDSSD product line. The RAIDDrive has a "turbocharged" DRAM cache and the RAIDDrive ES model for enterprise servers has a full battery backup for protection of data in a power loss situation. The RAIDDrive comes in three models, including the ES version and a WS version for workstations along with a GS version for gamers.
All of the drives connect to a PC with a PCIe 2.0 x8 interface and promise to deliver read speeds of up to 1.2GB/s with sequential wire speeds of up to 1.3GB/s. Super Talent says that it will reveal more performance details in June when the drives are officially available.
The maker also says that an optional feature of the series will allow the drives to be configured with internal RAID5 capability for extra data protection. The RAIDDrive ES is aimed at enterprise servers performing intensive applications like database transaction processing, business intelligence and virtualization. The WS model is aimed at workstation use for tasks including animation, video editing, oil/gas exploration, and CAD. The GS version is for gamers looking for a faster IO subsystem.
Super Talent COO, CH Lee said in a statement, "We are proud of the innovative intellectual property that our outstanding engineering team has developed. The RAIDDrive is just the latest in a series of patented products which enable us to provide differentiated products to our customers."

Laser Printers Emit Toxic Micro Dust.
Reprinted from:
Tuesday, April 07, 2009 by: David Gutierrez, staff writer.
NaturalNews.com
NaturalNews) A new study from researchers at the Queensland Institute of Technology has shed some light on exactly what factors lead laser printers to emit toxic particles into the air, making them the single most polluting piece of equipment in the typical office.
The same research team that initially showed the threat from laser printers conducted a study comparing two different printer models, the HP 2200 and the HP 1320n. They found that the dangerous particulates emitted by printers are apparently produced by an interaction between volatile organic compounds, ozone and heat.
Individual components of each printer, such as fuser rollers and toner, were heated separately in furnaces so that researchers could observe how they emitted particulates or VOCs in response to heat. They found that each component had a given threshhold under which emissions were nearly nil, a higher threshhold at which only VOCs were emitted, and yet another at which both VOCs and particulates were produced. This threshhold ranged between 100 and 200 degrees Celsius (for a used roller and for lubricating oil, respectively).
The researchers also operated the printers in different settings to measure either the nature of particles emitted or to measure how long the particles persisted. They determined that the HP 1320n emitted roughly 100,000 percent more particulate than the HP 2200, largely due to a different pattern of particulate release. While the HP 2200 reached peak particulate emissions within only a minute, the rate of emission dropped drastically after that. In contrast, the HP 1320n also reached maximum emissions in less than a minute, but that peak was much higher than the 2200s and emissions essentially remained elevated until the end of the print job.
Toner or paper type had only limited effect on VOC or particulate emissions, leading the researchers to conclude that printer design -- namely the level of temperature control -- is the biggest predictor of emissions levels.

Google Voice: A Dutiful but Klutzy Secretary
By COURTNEY BANKS,WSJ. 04/06/09
(See Correction & Amplification below)
At 10:24 p.m., a message pops up in my Gmail inbox: hey tony it's emily calling i just wanted to talk to you and i also wanted to see if you had alrighty the it's my started lunch because we need to know how many people are coming.
No, it's not a straggler that survived the spam filter: it's a voicemail message from my sister, Emily—freshly transcribed and delivered to my Gmail inbox. The "Tony" in question is me, Courtney (the cyber transcriber has particular difficulty with my first name).
I'm a bit confused about what the rest of the message means, till I click on the embedded sound file and learn that Emily wants to know if I've RSVP'd to her sorority's upcoming brunch. A few more clicks and I've responded to Emily with a text message—without fishing my cell out of my purse or dialing a number.
video
Worth It?: Google Voice
2:54
WSJ's Courtney Banks reviews Google Voice, a new phone-management service that offers voice mail transcription, international calling and a dedicated phone number for multiple phones.
This is courtesy Google Voice, a free calling and voicemail application that Google launched (to a limited group of subscribers) in mid-March. Google Voice operates under the premise that you don't need multiple telephone identities in order to have the convenience of more than one phone. Instead of calling your home phone, work number, cell, or smartphone, people can simply dial your "Google number," which then rings all or some of your phones (up to six).
You determine which callers reach which phones (i.e., if your mom calls, your cell and home phone ring; your boss goes to your Blackberry; an overly ardent admirer goes straight to voicemail). Google Voice also records, transcribes, e-mails, and archives your voice messages, lets you send texts from the Web, offers free U.S. and cheap long distance calling, and allows you to control how and when you take a call.
I spent a week testing the beta-version of Google Voice to see how well it achieves the revolution of simplicity and efficiency it promises.
The online interface is similar to Gmail's, and I can only assume that once fully launched, Voice will join its fellow Google family members—Calendar, Documents, etc.—at the top of your Gmail inbox for easy access. Once set up with my account, I entered the "real" phone numbers that I wanted to ring when people called my Google number. I added a few contacts, sent out a mass text alerting friends and family to my new Google number, and waited for the phone to ring.
[Google Voice]
A few minutes later, my phone starts to buzz; "Unknown Number" flashes on the caller ID. I answer, and a woman's voice announces: "Call from: Mom. To accept, press 1. ." You can set your preferences so that unlisted callers are asked to identify themselves before the call goes through.
Since I'm at work, I direct my mother to voicemail, but I decide to listen in first to see if her message is urgent. This feature allows your voicemail to function like your home answering machine: you can listen while the caller leaves a message, and opt to pick up. A minute later, the voicemail transcription and sound file arrive in my inbox.
The actual transcription (which is done by computer) is far from flawless—it doesn't seem like Google has assigned its most accurate automated typists to the task. Most messages I got looked something like the one above: I could make out the gist but only about 75 percent of the words were accurate. A message from my roommate Monique began, "Hey Connie it's Bernie."
Voicemail transcription is not novel, and a few other companies offer the service at a fee. To compare, I tested YouMail, which has several subscription levels ranging from $3.99 per month for basic service to $329 for a year of premium transcription. YouMail uses human transcribers, and the accuracy was near dead-on. Like Google Voice, YouMail sends the transcription as a text message straight to your phone.
Google Voice also offers free calling within the U.S., and extremely competitive rates for calls abroad (two cents a minute for much of Europe, China, and Japan). Google connects the international call and debits the cost from your Google account; your phone bill registers it as a local call. I called Vienna from my cell phone and was only charged a few pennies. I even checked my cell phone records to be sure.
Google Voice is like having your own personal switchboard operator and a dutiful but klutzy secretary. However, if you don't have phones literally dropping out of your pockets, the total switchover to Google Voice may be more trouble than it's worth. Many people, myself included, won't be too keen to take on yet another new phone number, train people to call them on it, and remember to dial the extra digits to make outgoing calls (so the Google number will register on the recipient's caller ID).
I don't deny that Google Voice has some brilliant features, many of which I'll use—I'm just skeptical whether it's brilliant enough to inspire a mass conversion.

SYMANTEC AND THE CONFICKER WORM
SEFUL PRODUCT INFORMATION: SYMANTEC AND THE CONFICKER WORM :
There has been a lot of news about the Conficker Worm this week and Symantec is on the front lines in protecting internet user’s private information from this malicious software. Here is some useful copy you can use for your sites to let customers know what they can do to protect themselves against the latest in internet threats.
Sometimes called Downadup or Kido, the Conficker Worm has infected a large number of computers around the world. As yet, not much is known about the virus or what it is specifically set to do but some researchers estimate that millions of computers have been infected with the threat since January. Current users of Symantec’s Norton security products are protected.
With the latest versions of Norton AntiVirus 2009, Norton Internet Security 2009, and Norton 360 Version 3.0, internet users can protect themselves against Conficker. If customers are unable to reach Symantec’s web site, they may already be infected. In that case, they will need to get to a computer that is not infected, download their specialized Conficker removal tool and run it on the infected machine before installing new antivirus software.
The Conficker worm allows its creators to remotely install software on infected machines but no one is exactly sure what it will do. What is assumed is that the worm will be used to create a botnet that will be rented out to criminals who want to send SPAM, steal IDs and direct users to online scams and phishing sites.
The worm mostly spreads across networks. If it finds a vulnerable computer, it turns off the automatic backup service, deletes previous restore points, disables many security services, blocks access to a number of security web sites and opens infected machines to receive additional programs from the malware’s creator. The worm then tries to spread itself to other computers on the same network.
The Conficker Worm specifically targets all users of Windows XP and Window Vista. Mac and Linux users are not vulnerable to this software.
Computers that are not configured to receive patches and updates from Microsoft and who are not running an up to date antivirus product are most at risk. Users who do not have a genuine version of Windows from Microsoft are most at risk since pirated systems usually cannot get Microsoft updates and patches.
Advice to Stay Safe from the Downadup Worm:
• Run a good security suite (like Norton Internet Security 2009 and Norton 360 Version 3.0)
• Keep your computer updated with the latest patches. If you don’t know how to do this, have someone help you set your system to update itself.
• Don’t use ‘free’ security scans that pop up on many web sites. All too often these are fake, using scare tactics to try to get you to purchase their ‘full’ service. In many cases these are actually infecting you while they run. There is reason to believe that the creators of the Conficker worm are associated with some of these fake security products.
• Turn off the ‘autorun’ feature that will automatically run programs found on memory sticks and other USB devices.
• Be smart with your passwords. This includes:
o Change your passwords periodically
o Use complex passwords – no simple names or words, use special characters and numbers
o Using a separate, longer password for each site that has sensitive personal information or access to your bank accounts or credit cards
• Use a password management system such as Identity Safe (included in Norton Internet Security 2009 and Norton 360 Version 3.0) to track your passwords and to fill out forms automatically.
• Run Norton Internet Security 2009, Norton AntiVirus 2009 or Norton 360 Version 3.0. You can also try Norton Security Scan.
