<p>An improved method and apparatus for servo control of the position of read/write head (18) with respectto a magnetic disk (10) is disclosed. The disk comprises permanently recorded position data information (12). Upon initiation of a head traverse or "seek" operation, a microprocessor is controlled to select predetermined portions of instruction sequences, all of which sequences are used in the event the seek is such that the head (18) reaches its maximum velocity. Otherwise, portions of the accelerate and decelerate command sequences are chosen together with constant velocity commands as necessary to ensure that the head (18) is decelerated smoothly to a stop at the appropriate position.</p> |
