APPARATUS AND METHOD FOR RECORDING AND REPRODUCING DATA ON RECORDING MEDIUM

摘要

An apparatus for recording and reproducing data on and from a recording medium and a method therefor are provided to add a data processor which performs a new data processing operation as using an existing data processor as it is when a recording and reproducing apparatus which supports a new-standard disk is to be developed, thereby using existing resources to the maximum. A master data processor(220) processes data. A slave data processor(230) processes other kinds of data different from the data of the master data processor(220). A multiplexer(240) selects one of interface signals outputted from the master data processor(220) or the slave data processor(230) to perform communication with a disk drive(250). The master data processor(220) controls operation of the slave data processor(230), and controls the multiplexer(240) to select the one of the outputted interface signals.
