Abstract:
A disc reproducing apparatus in which after a sector consisting of sync data, header data, and digital data, and data stored in a recording medium is sequentially read for the sector and is written in a memory, the data stored in the memory is sequentially read and is reproduced, comprising:a memory controller which controls writing of data to the memory and reading of the data stored in the memory, wherein the memory controller comprises:a write address generator which generates a write address corresponding to a location in the memory in response to a mode signal; anda counter mode controller which generates the mode signal to control the write address generator and switches a data reading and writing mode according to a control signal, wherein the modes for which the counter mode controller generates mode signals include a round mode in which the internal address of the memory generated by the write address generator corresponds to a same memory area as a currently specified memory area, a straight mode in which the internal address of the memory generated by the write address generator corresponds to a memory area after the currently specified area, and a retry mode in which the internal address of the memory generated by the write address generator corresponds to a memory area previous to the currently specified area, the generated address including an address corresponding to a memory area not immediately previous to the currently specified area; anda controller which controls the operation of the memory controller by generating a control signal which controls the operation of the counter mode controller.
