摘要： An apparatus to improve the positioning accuracy of a tracking arm in a disc system is disclosed. The apparatus has acceleration means for moving the arm, braking means to brake the movement of the arm, means for detecting run-out, and responsive means for removing the braking means in the event of run-out detected.

摘要： @ A disk storage system is disclosed comprising a rotatable disk, a cooperating magnetic head, positioning apparatus for positioning the head at different radial positions of the disk for reading and/or writing data on the disk, a baseplate for supporting the above, and control circuitry for preventing oscillation build-up in the baseplate from deleteriously interfering with system performance. The control circuitry is constructed and arranged to control the timing of head positioning operations so as to inhibit the reinforcement of baseplate oscillations.
