Abstract
PURPOSE: To make it possible to reproduce a satisfactory sound signal which is free from the crosstalk, by superposing a time compressed sound signal on an image signal at every 1 track at least, and recording it.
CONSTITUTION: The BBDs 18, 19 become a writing state and a reading state reciprocally and also the reading speed becomes two times or so as high as the writing speed through the contact change-over switches 27, 28 to which are applied the clock pulses of regular frequency synchronizing with the rotary head drum from the voltage control oscillator 23 of PLL, and also the clock pulses which pass through the 1/2 frequency divider 26. Accordingly, a sound signal which is supplied through LPF16 and the record reproducing change-over switch 17 is compressed to 1/2 times or so of the time division, it is subjected to frequency modulation by the modulator 32, LPF30, etc., and subsequently it is recorded into the magnetic tape 14 through one rotary head 13 of the two units. In this way, the sound signal which has been compressed to 1/2 times or so is superposed and recorded to the image signal, and at the time of reproduction, generation of the crosstalk can be prevented.
