Total dimensional stability compensation system and method for magnetic tape drive
Abstract:
A tape drive for use with a magnetic tape including two spaced apart servo tracks and a first data track includes a tape head, an actuator assembly, and a controller. The tape head includes two spaced apart servo elements that are each configured to read one of the two servo tracks, and a first read/write element that is configured to one of read data from and write data to the first data track. The tape head is positionable at a base head rotation angle relative to transverse to the length of the magnetic tape. The actuator assembly is configured to selectively rotate the tape head relative to the magnetic tape. The controller controls the actuator assembly to selectively rotate the tape head relative to the magnetic tape from the base head rotation angle to an adjusted head rotation angle that is different than the base head rotation angle based solely on servo information from the two servo elements reading the two servo tracks.
