ABSTRACT:
A data reproducing apparatus reproduces a data recorded or medium which has auxiliary data added to main data subjected to an error correction coding process. The data reproducing apparatus includes a signal processor, a memory, a comparator and a controller. The signal processor separates the main data from the recording data read out from the recording medium to implement an error correction decoding process thereto. The memory means stores the decoded main data from the signal processor. The comparator compares the last data stored in the memory with the inputted main data to the memory. The controller controls write and read operations of the memory and controls the comparison condition of the comparator according to the main data from the signal processor.
