PURPOSE:To attain the slow driving and the quick stopping, to decrease a cost and to improve reliability by minimizing a driving current impressed to a motor by a driving current changing-over means when an optical disk is discharged from a driving device. CONSTITUTION:A motor driving part 21 to drive a motor 3 supplies a driving current Id impressed from a current changing-over circuit 22 to a motor 3 and a rotation direction is changed over by signals S3 and S4 from a control part 20. Presently, when a cassette is discharged, a signal S1 is made low, the current Id is made into I1 and the rotation of the motor 3 is discharged by the signals S3 and S4. Consequently, the motor 3 is driven at low speed, a home position sensor 3 detects a cassette, and then, the signal S2 is trailed and a motor is quickly stopped. Thus, a braking mechanism is made unnecessary, a cost is decreased and the reliability is improved.
