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.
