Hitachi Global Storage Technologies (HGST) will later this year begin selling hard-disk drives based on perpendicular recording, a yet-to-be commercialized recording method that should enable engineers to continue increasing drive storage capacity beyond today's limits.

If you want to learn more about this new technology watch Hitachi's "Get Perpendicular"video.

It's a fun video with a toe-tapping track. Crank up the volume!
