Title: Magnetic disk device having disk cache write function
Inventor: SUGIYAMA TOSHIO
IPC: G06F3/06
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To attain the decrease of frequency disabling write cache performance because of buffer empty wait and the improvement of performance through a method for temporarily and sequentially writing write data into a saving area provided on a disk corresponding to write commands continuously issued by random access. SOLUTION: The continuous write to positions 21, 22 and 23 on a recording medium is temporarily and sequentially performed into the saving area shown by 20. When there is no host access, the data written in the saving area are returned to the positions 21, 22 and 23. Since the write end of write data to the saving area corresponding to the write command continuously issued by the random access becomes the end of write to the host requested position, seeking from the position 21 to 22 and from 22 to 23 on the disk is not required and a buffer can be made empty speedily just for that time.
