Abstract
In processing a video signal reproduced from a track of a magnetic disc (10), if the reproduction video signal, from one track of the frame recorded on two adjacent tracks, is stored in a memory (34), then the control circuit (20) determines whether the memory (34) should be used as a field memory or a frame memory based on a field/frame discriminating signal reproduced from the reproduced track. Therefore, error which occurs when only one of the two tracks is erased, can be prevented.
