Abstract

PURPOSE:To make approach to an ideal setting speed near a recording track, which is a purpose, by obtaining the real speed of a record reproducing head from a pulse time interval at a track cross time and changing a target speed in correspondence to difference from the ideal setting speed. CONSTITUTION:When a head 11 executes seek to the recording track of a disk 6, a pulse is outputted by a track cross detecting means 7 each time the head 6 crosses the track. The number of the remaining tracks to the recording track, which is a purpose, is counted by a control unit 8. When the number goes to be smaller than a prescribed number N, the time of N and N-1 is obtained by a timer means 9 and the real speed and the target speed are computed between N-1 and N-2. Then, the target speed is outputted by a target speed generating means 10 between N-2 and N-3. Thus, the head 11 is controlled. As this result, the approach to the ideal setting speed can be rapidly made near the recording track which is the purpose.
