<p>A method of positioning the read/write head onto a desired data track (344) in a multi-track record/player utilizes a plurality of registration stripes (381, 382, 383) to find the central axis of a data track. In one embodiment, each registration stripe has associated with it a recorded identification pattern or tone which may be sensed and used for identification purposes. Then, based upon the read amplitude output of the read head (103), the appropriate edge of a registration stripe (382) is detected and, from there, the read/write head (103) is moved directly onto the desired data track without any subsequent open loop movement. In an alternative embodiment, multiple edges are sensed and used in a calculation to determine the lateral displacement associated with the longitudinal centerline of a desired data track.</p> |
