Hitachi's division of storage technologies, Hitachi Global Storage Technologies, is expected to announce they will begin selling 1-terabyte desktop drives later this year. In order to increase storage capacities, HGST is employing perpendicular recording, which Macworld describes as: Perpendicular recording is perhaps the most significant near-term step in the evolution of hard-disk drive technology. The method is similar to the longitudinal recording used in today's drives in that it relies on magnetically charged particles for data storage. In today's drives, the north and south poles of the magnetic particles run parallel to the disc but in the new method they...
