Abstract
PURPOSE:To always and accurately detect recording termination, by setting an interval between a head for a control signal and an erasing head for the control signal larger than the recording mark of one cycle of the control signal on a tape, and detecting a miss-part where no control signal exists for a time longer than one cycle. CONSTITUTION:An erasing fixed head 8 which erases a control signal track and a fixed head 9 for recording and reproducing the control signal are provided in such a way that the erasing fixed head 8 precedes, and a separated distance between those two heads 8 and 9 is set longer than the interval of one cycle of a recording control signal on the tape 7. The mission part of the recording signal of the control signal is detected by moving the tape 7 in a forward direction to a reproducing state, and detecting the cycle of a reproducing control signal from the fixed head 9 for the control signal, and the missing part is detected as the recording termination. In such a way, it is possible to detect the recording termination accurately even when the tape is fed after completing recording.
