Abstract
An information signal recording disc is recorded with a stereoscopic television signal comprising a stereoscopic video signal and audio signals. The disc comprises a spiral track made up of a plurality of track turns, and video signals related to four fields are recorded on each of the plurality of track turns. Each track turn is time-sequentially recorded with right-eye and left-eye video signals of mutually different field numbers out of the right-eye and left-eye video signals of a simultaneous stereoscopic television signal in a sequence of field numbers together with audio signals, so that the right-eye video signal and the left-eye video signal are respectively recorded for a time period of two fields in each track turn. The right-eye and left-eye video signals related to identical fields are recorded side by side to each other in two mutually adjacent track turns. A predetermined sequence with which the right-eye and left-eye video signals are recorded on the spiral track is repeated with a period of eight fields.
