ABSTRACT:
A reproduced data processing circuit having a subcode delimit information generator to generate subcode delimit information, which indicates a delimiter of the subcode, in response to at least one of two subcode sync signals detected from the subcode included, together with digital audio data, in the demodulated output obtained by reading the data from a digital audio disc and demodulating the same. A time base correction is executed for both the digital audio data and the subcode delimit information. The delimiter of the subcode is identified on the basis of such subcode delimit information, and a linking process is executed for the digital audio data in the individual unitary subcode frames. The time base positions of the PCM audio data to be linked are settled exactly to thereby enhance the reliability of the linking process.
