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