Abstract

PURPOSE:To eliminate unnecessary signal parts practically, by changing the signal state to record a jump operation signal in a part, which is not concerned with the operation of the servo system, of a control channel and performing the fast-forwarding by this signal. CONSTITUTION:The output of a 1/2 power source voltage supplying circuit 1 is outputted to a control head 2 and a differential amplifier 3. The output of the differential amplifier 3 is amplified in an inversion amplifier 5 as well as a non- inversion amplifier 6, and outputs of amplifiers 5 and 6 are subjected to peak detection and comparison in a circuit 7 and are sent to a SW8. A logic circuit 15 controls SWs 4, 8, 16, and 17. The output of the inversion amplifier 5 is inputted to the logic circuit 15, a triangular wave generator 13, and a saw-tooth wave generator 14 through an upward pulse detector and multivibrators 10 and 11. In respect to operations of SWs 35-37 of a switch part 18, the SW36 is turned on and the SW16 is turned on for recording of a jump signal, and the SW37 is turned on and the SW17 is turned on for erasing of this signal, and the SW35 is turned on and SWs 4 and 8 are turned on for jump on, and SWs 35- 37 are turned off and the SW4 is turned on for jump off.
