摘要： A voice coil motor capable of quickly and precisely positioning a magnetic head with high precision is provided with a bearing rotatably supporting a head carriage without being influenced by a radial load. Two coils having radial sections contributing to generate a torque are provided to be rotatable in a magnetic space formed by a permanent magnet and a pair of yokes, and are layered along a central rotating axis in such a manner that an extension angle of the radial sections of one coil differs in direction from that of the radial sections of the other coil. When electric current flows, no radial load works, and a resultant force generated in these coils can be a couple of forces in the direction vertical to the movement direction of the magnetic head, so that the magnetic head can be quickly positioned with high precision, realizing a small magnetic disk device.

摘要： A head supporting device with a loading/unloading mechanism and a disk drive unit using the head supporting device. The head supporting device and a voice coil motor (VCM) make up a head actuator of the drive system. The head actuator has i) a support arm rotatable on a bearing, moving in directions along the radius of a recording medium and vertical to the surface of the medium; ii) a magnetically levitating head on a slider facing the medium; and iii) resilient member for applying force to the arm in a direction close to the medium. The VCM has a pair of yokes, a magnet, and a coil. When the head is lead to a head retracting position, the other end of the arm is pulled by the interaction of a magnetic member and the magnet at the resting position and adjacencies. This eases the load on the VCM, contributing to a compact and slim disk drive unit with toughness and rapid data-access.
