Abstract

PURPOSE:To enable data to be read immediately when an optical pickup arrives at a targeted position by supply a motor driving signal corresponding to the rotational frequency of a spindle motor at the targeted position at the time of moving the optical pickup to the targeted position. CONSTITUTION:When the music number designation button of an operating part 9 is depressed, a control part 8 detects the fact, and the number of tracks to the targeted position and the rotating speed of the spindle motor 2 when the optical pickup arrives at the targeted position are calculated from the absolute time information of the optical pickup 3 at the present position and the absolute time information of the targeted position. And the motor driv-signal MKS corresponding to the rotating speed is outputted to the spindle motor 2 while the optical pickup 3 is moved. As a result, the rotating speed of the spindle motor 2 arrives at the rotating speed corresponding to the position of the optical pickup when the optical arrives at the targeted position. In such a way, it is possible to start to read the data simultaneously with the arrival of the optical pickup 3 to the targeted position.
