Abstract
An actuator latch system of a hard disk drive selectively locks in place and releases a rotatable swing arm having a front end portion supporting a magnetic head and a rear end portion on which a voice coil motor (VCM) coil is disposed. The actuator latch system includes a notch in the rear end portion of the swing arm, and a rotatable latch lever having a front end portion including a hook and a magnet. The hook is received in the notch in the rear end portion of the swing arm to arrest rotation of the swing arm in a predetermined direction. The magnet of the latch lever faces a section of the VCM coil such that when the hard disk drive is started, the latch lever is rotated by a force generated due to current flowing through the section of the VCM coil faced by the magnet and the magnetic field generated by the magnet. The rotation of the latch lever prevents the hook from interfering with the rotation of the swing arm in the predetermined direction.
