Abstract
PURPOSE:To correct a tracking error more easily by providing a means for selectively generating either of a reference pulse including the pulse of a same frequency as the reference pulse different in frequency respectively but showing a prescribed ratio, and a means for simultaneously varying the frequencies of plural pulses. CONSTITUTION:A correction pulse generation means 80 is provided with a first pulse generation means 81, a second pulse generation means 82 and a third pulse generation means 23 which is conventionally similar. On the other hand, a frequency variable means 90 consists of variable resistors R0 which are provided in common between one end of respective resistant arrays of the first<=third pulse generation means 81, 82 and 23 and respective resistant connection terminals of timers IC24 in respective pulse generation means. Since the resistance values of the resistances connected with respective IC can simultaneously be varied by operating the variable resistors R0, the frequencies of the corrected pulses which are set in respective ratios can be shifted in common and speedy correction.
