ABSTRACT:
There is provided a disk recording and/or reproducing apparatus including: a disk mounting part; a clamp member holding a disk-shaped recording medium between the clamp member and the disk mounting part; and a support member movably supporting the clamp member. One of the disk mounting part and the clamp member has a magnet and the other has an attractable member attracted to the magnet. A rotating member is rotatably supported by the support member and a rotary elevating mechanism moves the rotating member up and down at a predetermined height by rotating the member. The clamp member is allowed to approach the disk mounting part by attracting the attractable member by a magnetic force of the magnet or to depart from the disk mounting part against a magnetic force of the magnet.
