Toshiba 40GB Perpendicular Magnetic Record Drives

freitasm writes "Toshiba is now shipping a 40GB 1.8" hard disk, the first in the industry based on the PMR (Perpendicular Magnetic Recording) technology. The disk stores 40GB in a single platter, and there are plans to release a 80GB version later this year. The first models are already being used on Toshiba's new Gigabeat MP3 players." It's all part of their plan to squeeze more bits onto the head of a pin.
