Controlling erasing of tracks of a recording medium used with a still video apparatus

A still video apparatus, comprising:

• means for recording image signals corresponding to one picture composed of at least one field on a plurality of tracks formed on a recording medium, said image signals being recorded with serial identification data associated with said image signals, said image signals being divided into luminance signals and color difference signals, in which each of said luminance signals and said color difference signals in each field are recorded on different tracks of said plurality of tracks in accordance with a predetermined order determined by said serial identification data;
• means for manually selecting at least one erasing mode from a plurality of erasing modes, said plurality of erasing modes comprising a first erasing mode that only effects an erasure of image signals belonging to one of a first field or a second field of a frame recording mode, and a second erasing mode that only effects an erasure of said color difference signals recorded on said tracks of said plurality of tracks;
• means for determining at least one track group that includes said tracks on which said image signals to be erased are recorded, based upon said serial identification data, in accordance with said erasing mode selected by said selecting means, said determining means determining tracks on which said color difference signals are recorded based upon said serial identification data;
• and
• means for erasing all image signals recorded on said tracks of said at least one track group, as determined by said determining means, in a single erasing operation.
