According to one embodiment of the invention, a disk drive apparatus includes a case, a disk-shaped recording medium, a drive motor, a head, a head actuator, and a latch mechanism configured to latch the head actuator and hold the head actuator at a retracted position when the head actuator receives an external force. A latch member of the latch mechanism is arranged to be movable between a latch position and a release position and has an abutment portion, which abuts the head actuator when the head actuator moves from the information processing position to the retracted position, and a latch claw which latches the head actuator. The abutment portion has a first abutment portion, which abuts the head actuator first, and a second abutment portion, which abuts the head actuator following the first abutment portion, and the first abutment portion being formed less rigid than the second abutment portion.

Disk drive apparatus

According to one embodiment, a disk drive apparatus includes a base, a recording medium, a drive motor, a head, a carriage, and a latch mechanism. The latch mechanism includes a latch member, which is supported on the base to be movable between a latch position and a release position, and a latch stop provided on the base and configured to regulate the movement of the latch member in a direction of the latch position. The latch member has a first abutment portion which abuts the carriage and moves the latch member from the release position to the latch position according to the movement of the carriage, when the carriage moves from the information processing position to the retracted position, a latch hook capable of latching the carriage at the latch position, and a second abutment portion which confronts to the latch hook with a gap at the latch position.
