Vast small hard drives fuel new consumer applications and smaller computers

November 8, 2009

Toshiba Introduces Two 1.8-Inch Hard Disk Drive Families for Both High Performance and Long Battery Life in Mobile Computing Applications | www.earthtimes.org

After its merger with Fujitsu, Toshiba is now the largest manufacturer of mobile hard disk drives (HDDs) (2.5 inch and 1.8 inch HDDs). Toshiba is also the largest manufacturer of 1.8-inch HDDs and the company has just introduced a HDD in this form factor with 320 GB storage capacity. This 2-disk 1.8-inch drive offers the highest storage capacity in such a small package and will enable more consumer and mobile computer applications

Optical disc drives being replaced by flash memory in computers?

November 4, 2009

PC makeover: slimmer profile, no DVD drive | www.mercurynews.com

Many PC makers are not including optical drives, especially for laptops and netbooks. Leaving out optical drives is being done not to reduce cost but to allow slimmer laptop and netbook computers. Flash memory with built in programs and entertainment content are now on the market in USB as well as memory card formats. Downloading content and applications has become more common, replacing one of the big uses for optical drives in computers. As flash memory $/GB declines and as write speeds for flash devices improve will these devices replace current optical disk physical distribution formats?

Rare earth metals ban by China could impact hard disk drive production

September 22, 2009

World faces hi-tech crunch as China eyes ban on rare metals exports | www.telegraph.co.uk

China has been the single largest supplier country for rare earth metals such as terbium, dysprosium, yttrium, thulium, lutetium, neodymium, europium, cerium and lanthanum. China is contemplating a ban of some of these metals and restrictions on supply on many others. Many vital technologies are dependent upon rare earth metals such as motors, hard disk drives, electronics and illumination. There are deposits of rare earth ores in the North America, South Africa, and Australia but it may take years to bring these online.

Dual Stage Actuator HDDs appear on SATA disk drives

September 21, 2009

Western Digital debuts 2 TB, 7200 RPM Caviar HDDs | www.techspot.com

Western Digital announced that their new 2 TB 7,200 RPM Caviar HDDs use dual actuators. Dual (actually dual-stage) actuators provide a coarser movement of the recording head to tracks using head arms moved by a conventional voice coil motor while a finer motion is provided using a piezoelectric actuator closer to the head. Dual stage actuators add some cost to the drive and increase servo control complexity but allow higher track density recording. Dual stage actuators had only appeared in some enterprise (high performance) HDDs from Seagate and other companies in that market to this point

HDD component vendors support increasing storage capacity

August 20, 2009

Head shop rolls out disk size roadmap | www.theregister.co.uk

TDK has shown a roadmap for HDD heads showing development of areal densities with time. Current mass produced products are 250 GB/platter and 500 GB/platter for 2.5-inch and 3.5-inch HDDs respectively. Full production of 320 GB/platter 2.5-inch drives is to start by December (thus close to 1 TB for 3 disks and 620 GB for 2 disks). Full production of 640 GB/platter 3.5-inch drives should begin in January 2010.

Holographic dreams, or visions?

August 18, 2009

Mitsubishi, Hitachi eye disc for cloud computing era | www.physorg.com

Hitachi, Mitsubishi and other Japanese companies are working together on a holographic optical disc that would store 1 TB of information. The companies say that this technology would be used in cloud computing to store data and information offline in interconnected databases. Holographic storage has been pursued by many companies over the last 20 years with no surviving commercial products.
