<p>A disk recording and/or reproducing device, comprising a disk drivingly rotating mechanism having a rotating shaft and a drive pin installed at a position eccentric to the rotating shaft, wherein the rotating shaft is inserted into a rotating shaft inserting hole provided in a disk and the drive pin is engaged with a drive pin engaging hole provided in the disk so as to position the rotating position of the disk and the disk is rotated drivingly for recording and/or reproducing information signals, whereby the drive pin can be prevented from being overlapped with the peripheral edge of the drive pin engaging hole when the disk rotating shaft inserting hole and the drive pin engaging hole drive the disk drivingly rotating mechanism from a position where the rotating shaft and the drive pin have been disengaged at a timing that the rotating shaft and the drive pin are not engaged by insertion with the rotating shaft inserting hole and the drive pin engaging hole of the disk, respectively, so as to displace the position of the drive pin.</p> |
