Abstract
The present invention is directed to a disk drive that utilizes a multi-stage actuator associated with two or more heads that are each associated with a separate disk surface to realize high speed data transfers. In one embodiment, the multi-stage actuator is used to simultaneously transfer portions of a data file between the heads and the associated disk surfaces and to perform simultaneous seek operations for the heads between data transfer operations. In another embodiment, the multi-stage actuator is used to alternatingly transfer portions of a data file between the heads and the associated disk surfaces and to perform alternating seek operations for the heads such that one head is transferring data while another head is performing a seek operation.
