Seagate claims 160GB laptop drive

Seagate technology has produced a 160GB hard drive for laptops.

The drive which is the highest capacity 2.5-inch drive on the market according to the company, was promised last year and is Seagate’s first laptop hard drive to use perpendicular data recording. Perpendicular data recording involves standing the magnetic fields that represent data bits upright. In most current drives these fields lay flat on the disk surface. Standing them upright means they take less space, enabling more to be packed on the disk and the storage capacity to be increased.

The Momentus 5400.3 drive is, as its name suggests, a 5,400rpm (revolution per minute) drive designed for notebooks. The version now has an ultra ATA/100 interface and a second version with a faster Serial ATA interface will be available later this year, said Seagate. By the end of this year, it hopes to have all of its products will using the technology, however no price was given for either drive.
