Abstract

PURPOSE: To prevent the damage of tape and to reduce the winding time, by providing the timing circuit which turns the capstan motor for a given time during tape winding and the mechanism which keeps the vacuum pressure the same as the state at normal operation.
CONSTITUTION: When winding signal is received externally, the winding operation signal 21 is generated, and when the tape start end marker is detected at the detection circuit 22 and a signal is generated, the winding operation discriminating circuit 23 produces the winding operation signal. This operation signal drives the capstan 5 in high speed with the capstan motor drive circuit 26 in matching with the timing signal from the timing counter 24, and the vacuum pressure of the vacuum buffers 6, 7 is kept the same as that at normal operation and the delay timing circuit 25 to measure the tape running distance is operated at the same time. Thus, since the recording part of tape is wound with the drive of capstan and suitable control of tape tension, the damage in the recording part can be avoided.
