ABSTRACT:
A hard disk drive comprises a voice coil motor for swinging a carriage about a support shaft, and a lock mechanism for locking the carriage in a desired position. The motor has a coil fixed to the carriage, and a motor magnet opposing to the coil and having an arcuate surface coaxial with the support shaft. The lock mechanism comprises a magnetic member attached to the carriage and movable in an arcuate path coaxial with the support shaft in accordance with the swing of the carriage, while opposing to the arcuate surface of the motor magnet, and a locking magnet provided near the arcuate path of the carriage, for attracting the magnetic member when the carriage is swung to the desired position. The arcuate surface of the motor magnet includes an opposing region which is opposed to the arcuate path of the magnetic member and a non-opposing region which is continuous to the opposing region. The motor magnet has a recess formed only in the non-opposing region.
