ABSTRACT:
A tape travelling drive circuit (25) of a magnetic video recording and reproducing apparatus enables a magnetic tape (1) to travel at a speed approximate to a value {2n.+-.(1/m)} times the travelling speed for recording (n being a positive integer and m being a positive integer excluding 1). A detector (34) detects an output level of a reproduced video signal. If the output level is higher than a predetermined level, the detector (34) stores the reproduced video signal in a storage circuit (35) for a specified period and at the same time provides the signal through a selector (32). If the output level is lower than the predetermined level, the reproduced video signal stored in the storage circuit (35) is read out and provided through the selector (32). Thus, even if the output level is lowered, a picture of good quality with little noise can be reproduced.
