MULTIPLE ACTUATOR DISK DRIVE

摘要

A multiple actuator disk drive (20) utilizes multiple heads (46a-j, 47a-j) associated with respective ones of multiple actuators (341, 342) to read data from and write data to all tracks on the surface of a disk. The positioning of each head by the respective actuators is controlled by embedded servo-information recorded in the data tracks. The data tracks have a density of greater than 2000 tracks per inch. Utilizing two actuators provides access times which are reduced with respect to the access times provided by disk drives having a single actuator and an increased data transfer rate.
