Abstract

PURPOSE:To operate correctly a tape counter by writing the code of the tape running direction at the recording time and reproducing a tape automatically for a short time once at the reproducing time to read the code and storing the tape running direction to set a device to the holding state. CONSTITUTION:When a track and a tape running direction are designated by an operation part to this running direction is sent from a code generating means 3 to a signal processing part 4 and is processed by the signal processing part 4 and is written on the tape together with an audio input Ain through a recording amplifier 5 by a recording head 6. When the tape is loaded at the reproducing time, the tape is reproduced for a short time once, and the track where the code is recorded is extracted by a track switching part 9, and the code is read through a signal processing part 10 by a code detecting means 11, and the code of each track is stored in a storage means, and the device is set to the holding state thereafter.
