  • Patent number: 4661729
    Abstract: A voice coil motor for a moving storage media actuator has a permanent magnet assembly wherein a radially polarized magnet is formed as sectors, with like sectors of the outer housing which forms a portion of the pole piece assembly. These sectors are then mounted on the remainder of the pole piece assembly for the magnetic actuator to form a cylindrical magnet and cylindrical outer pole piece. The sectors require no further attachment or adhesive in addition to the magnetic field and provides substantially zero clearance contact between magnet and pole piece, to afford a continuous magnetic path interrupted only by the working gap through which the voice coil travels.
