ABSTRACT:
A disk recording and/or reproducing apparatus includes a cover mounted on a main body for movement between open and closed positions, a disk presser unit operably mounted on the cover of the apparatus such that it cooperates with a spindle drive unit for holding the disk, a holder cover attached to the cover for movement therewith, and a controller to control the holder to permit movement of the disk presser when the cover is in the closed position, so that when the spindle unit and disk table are moved radially relative to the disk, the presser unit is moved as well.
