ABSTRACT:
A data reproduction apparatus for a disk medium is disclosed. The apparatus comprises a data reading section reading subcode data recorded on the disk medium and corresponding main data recorded therewith, a sub Q code acquisition section separating sub Q codes from the subcode data read by the data reading section so as to acquire a plurality of sub Q codes corresponding to a plurality of serial subcode synchronizing signal, the sub Q code indicating an absolute time of the subcode data in the disk medium, a first condition judgement section generating a signal when each of the absolute time indicated by the sub Q code is identical with the others, a second condition judgement section generating a signal when the absolute time indicated by succeeding sub Q code is later within a predetermined time than that indicated by preceding sub Q code, and a final judgement section judging whether correct reading of the subcode data is performed when the signal from at least one of the first condition judgement section and the second condition judgement section is detected.
