Abstract: Vibrations transferred to the outside are lessened and high performance against external vibrations and impact is maintained. Further, data is recorded and reproduced satisfactorily. A CD-ROM drive device is provided which is capable of reproducing data at a standard speed, a quadruple speed and a sextuple speed. When a disk is mounted to the CD-ROM drive device, TOC information is read in a playback state at the standard speed (ST1). Next, the disk is placed in a playback state at the sextuple speed and is set to a state held at a predetermined address position (ST2). It is distinguished using a tracking error signal, a control signal for a spindle motor, etc. whether the disk is either an eccentric disk or an unbalance disk (ST3). When the disk is found not to be either the eccentric disk or the unbalance disk, a playback speed is set to the sextuple speed. On the other hand, when the disk is found to be either the eccentric disk or the unbalance disk, the playback speed is set to the quadruple speed. When the disk is found to be the unbalance disk, the playback speed is reduced to restrain the generation of self-induced vibrations at reproduction.

Abstract: THERE IS PROVIDED A DISK DRIVE IN WHICH A BASE LIFTING MECHANISM (93) MAKES A FIRST DISK CHUCKING OPERATION TO PLACE AN OPTICAL DISK (2) ON A DISK MOUNT (27) BY ELEVATING AT LEAST A BASE (31) TO A DISK CHUCKING POSITION, LOWERS THE BASE (31) TO AN INTERMEDIATE POSITION BETWEEN THE DISK CHUCKING POSITION AND A DISK RELEASING POSITION SO THAT A DISK ROTATION DRIVING MECHANISM (28) SPINS THE OPTICAL DISK (2) WHICH WILL THUS TAKE ANOTHER PHASE, ELEVATES THE BASE (31) TO THE DISK CHUCKING POSITION AGAIN, AND MAKES A SECOND DISK CHUCKING OPERATION TO PLACE THE OPTICAL DISK (2) ON THE DISK MOUNT (27). THUS, THE OPTICAL DISK CAN POSITIVELY BE CHUCKED ONTO THE DISK MOUNT.

Abstract: PROBLEM TO BE SOLVED: To perform surely chucking operation of an optical disk for a disk loading part. SOLUTION: A base elevating mechanism 93 elevates at least a base 31 to a chucking position, performs chucking operation of a first time at which the optical disk 2 is loaded to a disk loading part 27, drops the base 31 to an intermediate position between a chucking position and a chucking releasing position, a disk rotation drive mechanism 28 rotation-drives the optical disk 2, after a phase of the optical disk 2 is deviated, the base elevating mechanism 93 elevates again the base 31 to the chucking position, and performs chucking operation of the second time in which the optical disk 2 is loaded to the disk loading part 27.
