Abstract

PURPOSE:To surely and stably record and reproduce optical information by suppressing speed variation in a recording/reproducing region, accompanied with turning over operation. CONSTITUTION:A speed correction circuit 23 operates when a holder 1 reaches a turnover region A in reciprocating operation, and outputs a constant voltage for a constant period, and adds it to a difference voltage in an adder 24. The added output is outputted to a power supplying part 19, and after being given an adequate gain, is supplied to a driving part 15. Therefore, when the holder 1 comes in the turnover region A from the recording/reproducing region B, at first, the speed of the holder 1 suddenly increases, and afterward, the centrifugal force of the holder 1 acts largely as a load on a motor 14, and consequently, the speed suddenly decreases a little below a set speed. Then, in a state that it comes from the turnover region A to the recording/reproducing region B, the speed increases slowly and returns to the set speed.
