  • Head-track alignment
    Patent number: 6937425
    Abstract: A head-track alignment system and method. An embodiment of the system comprises: a head assembly capable of detecting arrival of servo frames in a first and second servo track of a tape; an alignment processor coupled to the head assembly generating a head-track alignment signal based on a comparison of the arrival times of the servo frames in the first and second servo tracks; and wherein the head-track alignment signal can be generated while accessing the tape. An embodiment of the method comprises: determining tape tilt with respect to a head assembly of a tape drive while accessing a tape, and compensating for the tape tilt.
