Abstract

PURPOSE:To increase a wow and flutter characteristic with low cost and high accuracy, by processing the recording bias signal containing the information of the wow and flutter component and during the reproduction while the frequency of the bias signal is within a prescribed range and making use of the processed recording bias signal as a speed control signal. CONSTITUTION:A switch S1 is switched to the (a) side during the reproduction. A reproduced signal is obtained from a tape 4 when the tape has a stable travelling and then amplified by a reproduction amplifier 8. Then the recording bias signal component is extracted through a by-pass filter 11 to receive a shaping and division 12. After this, the face that the frequency is within a prescribed range is detected 13, and a switch S2 is set at the (c) side. Then the speed of a capstan motor 1 is controlled by a speed control signal which is obtained by giving a process 14 to the recording bias signal received the shaping and division 12. At the rise of running of the tape, the fact that the frequency is out of a prescribed range is detected 13, and the switch S2 is set at the (d) side. Then the speed of the motor 1 is controlled by a speed generator 2 and a control circuit 3 like in the recording mode.
