First Claim
Patent Images
1. A method for positioning an actuator of a disk drive in communication with a host, the method comprising:
- determining a target location for prepositioning the actuator to a position expected to decrease a physical access time for a subsequent command from the host before receiving the subsequent command from the host, wherein the target location is determined based on at least one of a characteristic of the disk drive, recent command activity of the host, and information provided by the host; and
moving the actuator toward the target location.
