ABSTRACT:
A still video device includes a magnetic head for reproducing a signal recorded on a floppy disk, a first switch for commanding a successive erasing mode, and a second switch for designating a kind of signal to be erased. The successive erasing mode is set by the first switch so that only a video signal or an audio signal is successively erased from a series of tracks, the signal to be erased being determined by the second switch. The first switch may be an exposure correcting switch provided for correcting an exposure. The second switch may be a select switch provided for selecting an operation mode of the still video device, such as recording, reproduction, and erasing.
