Perpendicular storage arrives on laptops

Seagate's new drive, the Momentus 5400.3, was being shipped as of Monday, the Scotts Valley, Calif.-based company said. The shift to perpendicular recording allows it to bump up the maximum capacity of its notebook drive to 160 gigabytes from 120 gigabytes.

The 2.5-inch drive costs $325, compared to about $240 for the 120 gig model. Seagate plans to extend the new recording technology to other notebook drives, as well its 1-inch drives used in handheld gadgets and 3.5-inch drives for desktop PCs.
