ABSTRACT:
A trapezoidal circuit is formed with a D/A converter circuit for receiving the sequentially varying count of a counter and the D/A converter circuit is caused to generate a trapezoidal wave whose slopes on both sides vary linearly. When a control signal is rewritten at the time a leader picking signal is written and erased, the control signal is rewritten upon receipt of the signal linearly varying from the trapezoidal wave generating circuit at the time the write operation is started and terminated.
