Abstract
PURPOSE: To perform reproduction suitable for a recording track automatically by controlling a pickup drive system by recording concentric recording tracks and a spiral recording track together on a discoid recording medium and by discriminating between the both in reproduction.
CONSTITUTION: In area (a), still pictures are recorded on concentric tracks and in area (b), motion pictures are recorded on a spiral track. In fan-shaped areas, a vertical synchronizing signal is recorded, but in the signal section, a retrieval information signal of every track is recorded superposing it. Here, retrieval signals are made different in addressing bit to make it possible to discriminate between areas (a) and (b).
