PROBLEM TO BE SOLVED: To provide a disk holding mechanism thinner than a conventional mechanism, and a disk unit equipped with this. SOLUTION: An optical disk holding mechanism 11 comprises: a disk-shaped disk table 13; and a clamper top 14. The clamper top 14 comprises: a cylindrical clamper base 21 passing through a mounting hole of an optical disk 12; and a movable member 22 holding the optical disk 12. The clamper base 21 is integrally provided in the center of an upper surface of the disk table 13, and forms a plurality of guide grooves having openings at the edge and radially extending. The movable member 22 is mounted in the respective guide grooves through a coil spring 23. The disk table 13 forms a leaf spring 24 at a position to be alternate to the movable member 22 in a circumferential direction. In the leaf spring 24, one end at a clamper base 21 side is fixed, and the other end being radially outside is a free end so that the plate spring 24 bends in a loading/unloading direction of the optical disk 12.
