特徴とするデイスク駆動装置。[Claims for Utility Model Registration] (1) An arm equipped with a recording/reproducing head at its tip, and a support member that is swingable about a support shaft and supports the arm so that it can move up and down relative to the disk. In a disk drive device in which a supporting member rotates toward the disk when the disk reaches a recording/reproducing position to bring the head into sliding contact with the disk to record and reproduce information, the supporting member protrudes on the side opposite to the head. a locking part that is provided and defines a position where the head is spaced from the disk; and a locking part that is capable of locking the head at the spaced position and when the disk reaches a preset position when the disk is inserted. A disk drive device characterized in that a locking device is provided which releases the locking state with the locking portion and presses the case portion of the disk at the time of release. (2) In claim (1), the locking device is rotatable and includes a locking end that locks the locking portion and a contact end that is rotated by contacting the case of the disk. 1. A disk drive device comprising: a rotor supported by a rotor; and biasing means for biasing a contact end side of the rotor in a disk ejection direction. (3) In claim (1), the locking device has a locking end on the free end side, and projects into the disk insertion portion when the disk is not inserted, and is pressed by the disk when the disk is inserted. What is claimed is: 1. A disk drive device comprising a spring member having a curved portion that extends in a direction parallel to a disk surface to release a locked state of a locked end.
