ABSTRACT:
During still reproduction, slow-motion reproduction and the like reproduction mode in a magnetic reproducing apparatus, a magnetic tape is travelled intermittently at a standard travel speed, i.e., at the same tape speed as that for recording, and a video signal reproduced over a period during which the magnetic tape runs at the standard travel speed is written into an image memory. During the standard travel speed period of the magnetic tape, a magnetic head correctly traces recording tracks on the magnetic tape and so the video signal of less noise is stored in the image memory. The video signal stored in the image memory is read out to provide for reproduced still and slow-motion output signal.
