ABSTRACT:
A disk apparatus comprises a carriage rotatably arranged in the case, and a magnetic head supported on the carriage. A voice coil motor for rotating the carriage includes a yoke fixed to the case, a magnet fixed to the yoke, and a coil mounted on the carriage and facing the magnet. A carriage locking mechanism for locking the carriage in a stop position includes a locking magnet and a magnetic member fixed directly to the yoke and the carriage, respectively. The magnetic member is attracted by the magnetic force of the locking magnet to lock the carriage in the stop position, when the carriage is rotated to the stop position. An elastic member is fitted on the locking magnet so as to abut against the magnetic member to relieve the shock and to define a predetermined gap between the magnetic member and the locking magnet when the carriage is rotated to the stop position.
