Abstract
A data reproducing apparatus for reproducing main data from a disc on which a data string comprised of main data and auxiliary data appended to the main data at intervals of predetermined lengths of the main data, which main data are previously error correction coded input digital data. The main data are separated from data read from the disc and error-corrected in a decoder. The error-corrected data are stored in a memory. The data stored in the memory are continuously read by a readout control circuit. Data patterns before and after connecting portions of the main data written in or read from the memory are compared in a comparator and the next data are continuously reproduced at a time point when the data pattern coincidence is detected in the comparator.
