Abstract

PURPOSE: To obtain a magnetic disk controller which is capable of high-speed transfer and has the bit unit price reduced by arranging plural general purpose magnetic disk devices in parallel to use them.
CONSTITUTION: Memory control circuits 2a to 5a access magnetic disk devices 10 to 13 through magnetic disk interface circuits 6 to 9 based on a inputted addresses. Pertinent data of the magnetic disk devices are saved in dual port RAMs 2 to 5. With respect to data transfer from dual ports RAMs 2 to 5 to a memory 16, interleave is applied through a system data bus 17 by memory control circuits 2a to 5a to transfer data at a high speed. Thus, data is transferred at a high speed, and the bit unit price is reduced.
