ABSTRACT:
A reproducing apparatus comprises an error correcting means which includes first and second input circuits for inputting first and second coded data read out via different series separately, first and second frequency converters for converting the respective timing frequencies of the first and second coded data to higher frequencies, a multiplexer for generating third coded data by time-division multiplexing the first and second coded data of the higher timing frequencies, and an error corrector for executing an error correction of the third coded data. The apparatus further comprises a decode means for decoding the third coded data processed through error detection and correction, and a data output means for outputting the decoded data. The first and second coded data of different series can be inputted in parallel simultaneously due to the first and second input circuits, and such coded data of the higher timing frequencies are time-division multiplexed into third coded data of a single series, so that a process of error correction can be executed in a simplified configuration with a reduction of the power consumption.
