摘要： A disk retaining mechanism that realizes a reduction of its thickness while maintaining a clamping force and a centering accuracy of the clamper, with a structure, in which: a guide (11) is disposed in a manner to closely confront a clamper retaining member (9); a clamper unit retaining portion of the clamper retaining member (9) has such a shape that a part of which an entire circumference is cut out; a clamper unit for depressing a disk (13) is provided with a disk holder (3) having an engagement projection (M); and an annular engagement groove (F) formed in a turntable (7) for loading the disk (13) is arranged below an upper end of a main shaft (8) that transfers rotation of a motor unit (10).
