    摘要： A magnetic disk device comprises a magnetic disk in which a data zone is formed. An actuator has a voice coil and a head slider carrying a magnetic head, the actuator being swung to move the magnetic head over the disk between an innermost position of the data zone and an outermost position of the data zone. A magnet has a magnetization center and is opposed to the voice coil so that a voice coil motor which swings the actuator is formed, the magnet having a north pole and a south pole confronting each other via the magnetization center. The magnetic disk device is provided so that a deviation of a center of the voice coil from the magnetization center when the magnetic head is in the innermost position of the data zone is substantially equal to a deviation of the center of the voice coil from the magnetization center when the magnetic head is in the outermost position of the data zone.

    摘要： A magnetic disk apparatus includes an actuator including a magnetic head, a coil which forms a voice coil motor, and a coil arm which supports the coil, wherein the magnetic head can be rotated or swung by the voice coil motor so as to be positioned at any position on a magnetic disk, a magnet which forms the voice coil motor with the coil, and a latch mechanism for controlling the actuator so that the actuator is situated at a designated latch position in a non-operation condition. The latch mechanism is formed by the magnet and a magnetic metal piece provided to the coil arm, an extended part is formed at the magnetic metal piece, and the extended part is formed and positioned at a strong magnetic force generation part of the magnet when the actuator is positioned at the latch position.
