Abstract
In a magnetic recording and reproducing device for recording a video signal intermittently by a rotary magnetic head, a capstan motor is rotated by .alpha. or .alpha./.beta. pulses applied to a pulse generator for moving a magnetic tape exactly a length for one track or 1/.beta. of that length, .alpha. being a positive integer other than a prime number and .beta. being a positive integer other than 1, so the head can scan just one track correctly.
