ABSTRACT:
An apparatus is disclosed which is arranged to record a video signal in first areas respectively provided in a multiplicity of tracks on a recording medium and also a digital still-image signal in second areas which are respectively separated from the first areas. In the apparatus, while the digital still-image signal is being recorded in the second areas, the video signal is always recorded in the first areas, whereby it is possible to prevent occurrence of an uncomfortable phenomenon, such as formation of a scene devoid of a substantial image, during reproduction from the first areas. In addition, an analog still-image signal, representative of an image identical to an image represented by the digital still-image signal recorded in the second areas, is repeatedly recorded in the first areas during a predetermined time duration, whereby it is possible to facilitate search of a still-image signal recorded in the second areas. In addition, the digital still-image signal is recorded in the second areas at intervals of a predetermined period during recording of an analog moving-image signal in the first areas, whereby it is possible to record as many still images as possible.
