Disk device

A disk device provided with a rotatable bar-shaped fixing means which forms a groove on an outer periphery and which is loosely fixed to an inner diameter of a disk and a support means which abuts with a section of the surface of said disk, forms a support section which supports a section of said disk and forms a projection which engages to slide freely in said groove on an inner peripheral section and said projection slides in said groove and said support means is displaced in a direction of a rotational axis of said disk in response to rotations of said fixing means.

A disk device adapted to load a plurality of disks in said device is provided with a rotatable bar-shaped fixing means which forms a groove on an outer periphery and which is loosely fixed to an inner diameter of said plurality of disks and a plurality of support means which are provided on each disk, which abut with a section of the surface of said disk, which form respective support sections which support said disk and which form respective projections which are engaged to slide freely in said groove on an inner peripheral section and said projection slides in said groove and said plurality of support means is displaced in a direction of a rotational axis of said disk in response to rotations of said fixing means.

A disk device comprising a disk insertion/ejection mechanism performing insertion and ejection of disks to the inside and outside of a device, a disk position determination mechanism determining a position of said disk to a fixed position, a disk support mechanism supporting a plurality of positions of an outer periphery of said disk, a disk playing mechanism performing a playing operation of said disk, and a disk loading mechanism loading a disk by supporting an inner diameter of said disk.
