ABSTRACT:
An information processing system processes identification of a track address and a sector address, control of timing, control of reading and writing of data and error checking with reduced intervention of a CPU to a magnetic disc unit so that the throughput of the CPU is increased and performance for data processing is improved. A predetermined number of sectors are processed in sequence, and a greater number of sectors than the number of sectors in one track can be processed by hardware implementation. This system can also control magnetic disc units having different formats.
