According to one embodiment, a disk drive includes a carriage supporting a head configured to perform information processing for the recording medium, and a latch mechanism configured to latch and hold the carriage in a retracted position when an external force acts on the disk drive with the carriage being in the retracted position. The latch mechanism includes a latch member pivotable around an central axis between a latchable range and a released position. The latch member is configured to pivot in a latching direction within the latchable range before the engaging portion of the carriage starts to move when a rotational impact externally acts in a direction to pivot the carriage toward the information processing position with the carriage and the latch member being located in the retracted position and the latchable range, respectively.
