A CD subcode transfer system includes a means for receiving a CD signal and outputting, along with a subcode, digital data derived from the CD signal after the digital data is error corrected and demodulated. The CD subcode transfer system also includes a means for determining whether a CRC check bit for Q channel data of the subcode is correct and for determining whether the Q channel data is correct upon comparison of the Q channel data with preceding Q channel data. In addition, the CD subcode transfer system includes a means for transferring the subcode and attaching the subcode to the digital data when the CRC check bit is determined to be correct and the Q channel data is determined to be correct.
