Patent ID: 7921434

Claim:
A disk device comprising: a casing; an insertion opening formed in the casing; a transfer mechanism provided adjacent the insertion opening; a control unit configured to control the transfer mechanism; a detecting mechanism configured to transition to a first detection state if an object is inserted into the insertion opening, and configured to transition to a second detection state if the object inserted is determined to be a disk of a first diameter; wherein the transfer mechanism carries the disk into the insertion opening at a first carry-in speed after the detecting mechanism transitions to the first detection state; and wherein if the detecting mechanism transitions to the second state within a predetermined monitoring period after the detecting mechanism transitions to the first detection state, the control unit controls the transfer mechanism to carry the disk into the insertion opening at a second carry-in speed so as to facilitate a carry-in operation of the transfer mechanism, the second carry-in speed being greater than the first carry-in speed.
