Abstract

PURPOSE: To make it possible to record and reproduce information from the start of a magnetic tape parts by adding a magnetic tape parts detection unit consisting of an oscillator circuit, a control circuit and a switching circuit.
CONSTITUTION: Oscillator circuit 6, control circuit 7 and switching circuit 8 are added to a recording and reproducing circuit of a cassette deck, etc. When a power source is supplied to this unit to make a recording state, a switching signal is generated by control circuit 7, and switching circuits 8a and 8b are switched. Simultaneously, oscillator circuit 6 is turned on, and the output is supplied to recording head 1 through recording circuit 3. Then, information is recorded when magnetic tape part 9b of magnetic tape 9 reaches head 1, and simultaneously, information is reproduced by reproducing head 2. Receiving these reproducing signals, circuit 7 returns circuits 8a and 8b to original states and turns off circuit 6. The operation above is performed at a reproducing time. As a result, information can be always recorded and reproduced from the start of the magnetic tape.
