PURPOSE:To alternately and simultaneously reproduce video information by simultaneously recording and forming the video information of both sides on the two adjacent spiral or concentrical circle form recording tracks of a video disk record. CONSTITUTION:The video disk record D simultaneously records the video signal for the right eye VR and the video signal for the left eye VL by two recording beams, thereby, double spiral recording tracks T1, T2 of a constant linear velocity are formed. Accordingly, on the adjacent recording tracks, the video signal of two channels and a sound signal of two channels are simultaneously recorded. Two sets of video cameras CR, CL are synchronously driven by a common external synchronizing signal, pick up the image of a common object from different directions of both sides, thereby, the video signal VR for the right eye and the video signal VL for the left eye are conducted and at the same time, the right side sound signal AR and the left side sound signal AL obtained from external microphones MT, ML are conducted out from the cameras CR, CL. Thereby, the video information of both sides can be alternately and simultaneously reproduced. |
