Abstract
PURPOSE: To eliminate both the rotary wait of the magnetic record medium and the positioning wait of the magnetic head and thus to realize the high-speed reading and writing of the data by adding the high-speed memory part and the supervisory circuit to supervise the contents of the high-speed memory part to the mass memory device.
CONSTITUTION: Magnetic disk device 3 is connected to mass memory device 1 used in the electronic computer. And high-speed memory part 81 featuring the capacity equivalent to several tracks on magnetic disk medium 9 and divided in each track unit is provided to device 3, along with contents supervisory circuit 82 supervising the memory contents of part 81. Then address coincidence circuit 82a plus initial/final circuit 82b are added to circuit 82, and then the reading contents of medium 9 is read in a high speed to part 81 via circuit 82 to be sent to the central process circuit. At the same time, the writing contents of medium 9 is written into part 81 from the central process unit. After this, the writing is performed to medium 9 via circuit 82.
