Toshiba Corporation today announced commercialization of two
advanced 1.8-inch hard disk drives (HDD): the MK1626GCB offers a
storage capacity of 160GB, the industry's largest in this form factor,
while the thin and light MK8022GAA has a capacity of 80GB. Both drives
are designed for mobile devices, such as portable media players.
Toshiba has started to ship the MK8022GAA, and is also shipping
samples of the MK1626GCB.
The new drives employ an improved read-write head and enhanced
magnetic layer that boost recording density, and achieve an areal
density of 353 mega-bit per square millimeters (228 gigabits per
square inches). The MK1626GCB adopts CE-ATA, an HDD interface that
optimizes performance in consumer electronics applications.
Small form-factor 1.8-inch HDDs are found in increasingly diverse
applications, from mobile notebook PCs to portable media players and
digital movie cameras. The HDD market is driven by growing demand for
larger capacity drives that can store movie files and still pictures
and music data, and support the transition to high-definition video
and richer image and sound files. The new 1.8-inch drives do just
that: they are small and light and offer unrivaled capacity that will
allow storage of HD movies and countless digital still images and
music files in small personal digital devices.
The new drives are also environmentally conscious. The MK1626GCB
improves energy consumption efficiency(2), as defined by Japanese law,
to 0.002W/GB, a 33%(3) reduction. Both drives are also RoHS-compliant.
Toshiba will feature the new drives at DISKCON USA 2007, organized
by the International Disk Drive Equipment and Materials Association
(IDEMA), in Santa Clara, California, from September 19 to 20.
(1) The industry's largest commercially available capacity in a
1.8-inch hard disk drive, as of September 6, 2007 (source: Toshiba)
(2) Energy consumption efficiency is calculated based power
consumption divided by formatted capacity, as defined by Japanese law.
(3) Comparison based on Toshiba's current 1.8-inch HDD
(MK1011GAH).
