<p>PURPOSE:To perform accurate positioning and various controlling automatically with the signals having been recorded in a magnetic tape by providing a first filter, oscillators and second filters allowing the passage of only the specified frequencies corresponding to said oscillator. CONSTITUTION:The output of a microphone 13 passes through a first filter 19 which cuts the specified frequency band of the recording information signal and is recorded in a magnetic tape 25. As a switch 21 is changed over, the position signals indicating recording start position, etc. are recorded by an oscillator 221 which outputs letter signals and an oscillator 222 which outputs collect signals. At the reproducing, the signals are reproduced through changing over of a switch 27 and the information signal is selectively supplied to second filters 281, 282. Positioning controlling is performed by outputting the motor stop signal through a flip-flop 30. Hence, various controlling such as accurate positioning, stopping, reproducing, etc. may be readily and automatically accomplished and operating characteristic improved.</p> |
