Abstract
In a magnetic recording and reproducing apparatus for reproducing a video signal recorded on a video track of a magnetic tape by pair of magnetic heads arranged in a rotation drum so as to oppose to each other at an angle of 180 degrees, while rotating a capstan for moving the magnetic tape in the longitudinal direction, a memory controller controls the reproduced video signal to be written into and be read out from two memories, each of which stores a video signal of at least one field. Then, a quality of image judgment circuit judges a part of the reproduced video signal having a quality of image higher than a predetermined threshold quality level, among a plurality of parts of the reproduced video signal obtained through scan of a pair of magnetic heads. In a slow-motion reproduction, the memory control circuit controls the part of the reproduced video signal having the higher quality of image to be written into one of the two memories, whereas the memory control circuit simultaneously controls a further reproduced video signal to be read out from another one of the two memories.
