ABSTRACT:
The present invention relates to the improvement in an apparatus for reproducing information from a card-like optical information recording medium including tracks for guiding and tracks for information. At least three light spots are formed in said card-like recording medium by light-spot forming means. Signal detection means then detects focusing control signals and tracking control signals by scanning said tracks for guiding with a spot among said light spots. Further, signal reproducing means reproduces information signals of plural tracks by scanning the information tracks with the remaining at least two light spots. The reproduced information signals of the plural tracks are stored in plural memories separately for each track. Subsequently, read-out means sequentially and successively reads the stored information by the time sharing system from each of the plural memories with a speed larger than that when said reproduced information has been input.
