Abstract

PURPOSE:To enable to switch tape run speed automatically, by detecting the control signal recorded for a given time at the audio test recording, at reproducing, and switching the tape run speed into the set speed at recording through this detected output. CONSTITUTION:When recording starts by a recording button 3, the output signal of a pilot signal generating section 2 is recorded on a magnetic tape 8 via an input selector switch 5 by a given time (t) with the operation of a time set circuit 4, through a recording head 7. After a given time (t), the input selector switch 5 is connected to an input terminal 1 again, and audio signal is recorded on the magnetic tape 8. The pilot signal is detected at a detection section 12 and frequencies are detected at a frequency detection section 13, the output signal of which is input to a tape speed detection section 14 to control the rotating speed of a capstan drive motor 17 by a tape speed set section 15 and a capstan drive motor control section 16.
