ABSTRACT:
A video recording apparatus used for a television system and the like writes video information on a track formed on a recording medium in a writing direction which directs from a predetermined start position to a predetermined end position of track by use of a head. Thereafter, the video information is read from a desirable designated positon of the track in the writing direction. The read video information is reproduced and then its corresponding pictures are displayed on a display unit of the television system. This video information is not outputted from the recording medium in a period while the head returns to the predetermined start position of the track after the video information at the predetermined end position of the track is read out. So, this video recording apparataus can provide a memory which stores the video information and then outputs the video information during such period. Thus, the video information can be continuously obtained. Preferably, the recording medium is constructed by an optical disk or an magneto-optical disk, the memory is constructed by a semiconductor memory such as a random-access memory (RAM), and the predetermined start and end positions are innermost side and outermost side of the track.
