Super-large capacity data storage drive.

摘要

A fast access high capacity data storage system includes a disk-based storage system employing a plurality of storage surfaces (2). Selected storage surfaces of the plurality thereof include a plurality of data access heads (4) in data communication therewith. Means (6) is provided for allowing concurrent data transfers through this plurality of data access heads (4). Performance is further improved by monitoring frequently accessed data records and transferring them to recording surfaces less frequently in use. Means (48, 49) is also taught for moving the data access heads (4) of the plurality to other recording surfaces (2) to decrease access bottle-necks thereon.
