  • Method for calibrating a tape media using staggered calibration tracks
    Patent number: 6801383
    Abstract: A staggered calibration track comprising a plurality of calibration tracks for use positioning a tape drive tape head for reading and writing data to and from multiple data tracks. The staggered calibration track is written by positioning the write head to a predetermined location and moving the tape media horizontally as the vertical position of the tape head is incremented in a stepwise alignment. Locating one of the plurality of calibration tracks is accomplished by positioning the read head at the predetermined location corresponding to the edge of the particular calibration track and moving the tape media horizontally as the read head output is recorded. The particular calibration tracks vertical position is derived using the average read head output.
