Filed: 1989-10-02
Abstract: PURPOSE:To automatically perform rewinding by providing a counting means and counting signals equaling the number of tape traveling control CTL signal recorded from the time of starting the recording of data while rewinding a magnetic tape, thereby stopping the magnetic tape. CONSTITUTION:A recording means 16 performs an action for recording the data and the CTL signal on the magnetic tape 2, and the CTL signal outputted from the recording means 16 is inputted in the counter 24. A rewinding command 18 is inputted in the controller 21 for a fixed time which is until the counter 24 finishes counting as to accurately rewind the tape to the position of starting recording. After counting the signals equaling the number of the CTL signal recorded from the time of starting the recording of the data while rewinding the tape 2, the tape 2 is stopped. When the CTL signal is detected by the counter 24 at such a time, a counted value is decremented by one. When the counted value is zero, the command of stopping the rewinding of the tape is transmitted to a stop means 17 so as to automatically stop the tape 2.
