Disk device

Abstract

A disk device is provided with a plurality of rotatable disk support means which form a support section which supports a section of a peripheral section of a disk, and a support control means which rotates said plurality of disk support means based on an operation of said disk and which controls a support state of said support section with respect to a peripheral section of a disk.

What is claimed is:  
     
         1 . A disk device comprising a plurality of rotatable disk support means which form a support section for supporting a section of a peripheral section of a disk, and a support control means which rotates said plurality of disk support means based on an operation of said disk and which controls a support state of said support section with respect to a peripheral section of said disk.  
     
     
         2 . The disk device according to    claim 1   , wherein said support control means displaces said support means after the completion of a disk position determination operation of said disk to a fixed position in the device.  
     
     
         3 . The disk device according to    claim 1   , wherein when said support control means performs a disk playing operation, the support means is displaced in a direction of a rotational axis of said disk so that said disk determined to a fixed position is set to a playing operation position.
