New Hard Drive Head will Increase HDD Capacity to 4TB

" New Head for Hard Drive(HDD), new Head is being developed. And will be
released at 2011. It's a long time:D. This Head can write datas with smaller
size than the HDD Head now."
Hitachi develops new hard drive head technology that will increase storage capacity to 4TB by 2011

Hitachi recently announced that it has achieved a breakthrough in hard drive read-head design.

This breakthrough has produced read-heads in the 30-50 nanometer range, approximately 2,000 times smaller than the width of an average human hair. This new technology is called current perpendicular-to-the-plane giant magnetoresistive heads.

Giant magnetoresistance principles won scientists Albert Fert and Peter Grunberg the 2007 Nobel Prize for Physics.

These new heads will allow Hitachi to expand storage capacity in standard 3.5-inch desktop hard drives to 4TB and extend 2.5-inch laptop hard drives to 1TB of capacity. Hitachi says that it plans to integrate these new heads into hard drives starting in 2009 and that the technology will reach maturity in 2011.

The first products to reach market in 2009 will use recording heads of 50nm and products with recording heads of 30nm will hit market in 2011. Hitachi representatives believe the new heads will allow for storage densities of up to 500GB per square inch. The current highest capacity drives from Hitachi can only pack in 200GB per square inch.

Another benefit of the significantly smaller heads is that the hard drives will product less noise. Test products using 50nm heads produced 40dB of sound while the 30nm heads produced 30dB. Large capacity hard drives that produce less noise will be a welcome addition to digital video recorders.

ZPower Pushes Silver-Zinc Batteries as Alternative to Lithium-Ion

" Longer Battery Life course make more comfortable and more mobile. Now ZPower making battery just like we want a longer life battery."
ZPower promises 30 percent greater power density than lithium-ion cells

When it comes to mobile devices, battery life is paramount. Whether it’s a mobile phone, laptop or MP3 player; long battery life is an oft-requested feature by consumers.

Most of today's battery-powered devices make use of lithium-ion batteries which come with their own set of problems. As witnessed by the massive recalls last year of Sony-manufactured batteries, lithium-ion batteries can sometimes present a safety hazard.

Auto giant Toyota even shunned lithium-ion batteries for its next generation Prius. The company again cited safety concerns with the decision to stick with nickel-metal hydride batteries. Having a notebook catch fire due to faulty batteries is one thing, but having a $23,000 Prius rolling down the street on fire presents its own set of safety and legal challenges.

ZPower is looking to supplant lithium-ion technology with a battery chemistry that is safer and has improved energy output. The company had its new batteries on display this week at the Intel Developer Forum.

The ZPower batteries have an energy density that is 30 percent higher than that of lithium-ion batteries. According to ZPower president and CEO Ross Dueber, the batteries can even be safely overcharged to allow for additional runtime.

ZPower batteries are composed of a composite polymer zinc anode, layered separator and a nano-particle silver cathode. Since the cells used in ZPower's batteries are water-based, they are as safe to use as traditional alkaline batteries.

The zinc and silver used in the batteries are also 95 percent recyclable. ZPower will have a program in place in which customers can recycle their used batteries and get reimbursed for the value of the silver and zinc recovered. Customers will receive a check or receive credit towards the purchase of new cells according to Dueber.

All is not well, however, with ZPower's batteries. Pre-production batteries are only good for about 100 cycles compared to around 300 cycles for lithium-ion batteries. ZPower hopes to increase this figure to 200 cycles by mid-2008 and to 300+ cycles by 2010.

Due to the difference in voltage and battery chemistry of silver-zinc batteries, they are not at their most efficient when used in existing lithium-ion based devices. In other words, ZPower's batteries would be best suited for newly designed notebooks, mobile phones, etc. which can better cope with silver-zinc battery characteristics.

There is also no pricing information available for ZPower’s batteries in relation to traditional lithium-ion counterparts. And then there’s the issue of market adoption of silver-zinc batteries. As of now, ZPower only has one major OEM onboard to use its battery technology in notebooks, but Dueber declined to name the company.

Internet Explorer 7 Now Available to Pirates

" Microsoft just made a new version of Internet Explorer that doesn't need Windows Genuine Validation,  that's mean non-Genuine Windows can now upgrade their Internet Explorer, without any other program. But what are their aiming, is there anything that like spyware?? We don't know."
Microsoft has released a minor update to Internet Explorer 7 for Windows XP, removing the requirement for users to be validated through the company's Windows Genuine Advantage program. This means those with non-legitimate or pirated copies of Windows can now upgrade their browser.

IE7 was released to the public nearly a year ago, but has yet to overtake its predecessor as the most used Web browser. The removal of the WGA requirement is sure to boost install numbers over IE6, and -- as Microsoft notes -- in turn protect more users from security threats on the Web.

Although it continues to update IE6 for Windows XP with security fixes, the aging operating system is nearing the end of its mainstream support. In addition, IE7 includes a phishing filter that Microsoft says protects consumers at a rate of 900,000 times per week, along with native support for Extended Validation SSL Certificates to prevent fraud.

While the carrot-and-stick approach with WGA has been used to reduce piracy and catch unscrupulous resellers, Microsoft likely decided that those willing to validate their OS in order to upgrade to IE7 would have already done so in the past year, and those that have not would never do so.

Microsoft has made a number of minor changes to IE7 for Windows XP users as well. The menu bar is now enabled by default, and the "first run" experience and product tour have been expanded. An MSI installation is also now available to IT administrators.

Windows XP users can download the new IE7 release via FileForum, or wait for it to be delivered via Automatic Updates.

USB 3.0 to Bring 10x Speed Increase in 2008

" USB 3.0 is beign developed. It's 10x faster. Hope it coming soon. "

Intel discusses its plans for USB 3.0 technology

During Patrick Gelsinger's keynote at the Intel Developer Forum (IDF) today, Intel made a small announcement regarding a group of companies who are now working together to create a "superspeed personal USB interconnect” with 10 times the speed of the current generation technology of USB 2.0. The USB 3.0 Promoter Group -- which consists of Intel, Hewlett-Packard, NEC Corporation, NXP Semiconductors, Microsoft and Texas Instruments -- looks to make several other major changes.

Along with the 10x speed difference between USB 3.0 and the current generation, the USB 3.0 Promoter Group is taking power consumption and better protocol efficiency into consideration while designing 3.0. USB 3.0 will be able to use the same architecture of wired USB, though no other specific details are yet available.

To help drive home the importance of USB technology, Gelsinger pointed out the usual USB devices everyday users have in their homes and offices: keyboards, mice, speakers, cameras, etc. He also introduced a number of novelty items that are powered by USB including refrigerators and mittens.

"USB 3.0 is the next logical step for the PC's most popular wired connectivity," said Jeff Ravencraft, Intel technology strategist and USB Implementers Forum (USB-IF) president. "The digital era requires high-speed performance and reliable connectivity to move the enormous amounts of digital content now present in everyday life. USB 3.0 will meet this challenge while maintaining the ease-of-use experience that users have come to love and expect from any USB technology."

Specific USB 3.0 specifications should be available sometime in the first half of 2008.

Researchers Develop Nanowires for Storing Computer Data

" New Storage is just developed, it can store datas for 100,000 years, and also reading 1000 times faster. But what market they targetting? I think it's for Office and not for home, price is still unavaiable. Hope it will be for home user too. "
Nanowires store data for 100,000 years and read 1000 times faster than current data storage methods

With all the fuss about solid-state drives ever since CES 2007 -- centering on faster boot times and reducing random access times in accessing data stored on a solid-state memory module -- it is still only a matter of time until the next big discovery makes SSD technology obsolete.

A researcher at the University of Pennsylvania named Ritesh Agarwal and his colleagues have developed nanowires capable of storing computer data for 100,000 years and retrieving data 1000 times faster than current storage systems.

The nanowire technology also consumes less energy and requires less space than current memory technologies. “This new form of memory has the potential to revolutionize the way we share information, transfer data and even download entertainment," said Agarwal.

The technology is based on a self-assembling nanowire of germanium antimony telluride, which is a phase-changing material that switches between amorphous and crystalline structures -- the key to read/write memory. Agarwal also claims in tests the data writing, erasing and retrieval process lasted a mere 50 nanoseconds and consumes only 0.7 mW of electricity per bit.

The technology is said to be scalable to the terabit-level. At this time, there is no way to know when or if this technology will ever see mass production and ultimately replace current forms of flash and magnetic storage in computers.
