Appeal No. 1997-3851
Application No. 08/355,210
for, when a write instruction is issued to one of said data
disks while said data disks execute an operation which
prevents said data disks from inputting and outputting data,
temporarily storing data to be written in said one of said
data disks” as recited in Appellants’ claim 27. Satoh teaches
in column 5, lines 31 through 45, that a disk cache 5 can be
used to place a directory DIR whose rewriting frequency is
maximized in order to decrease the number of excesses to the
data optical disk drive 6. Thus, Satoh does not teach or
disclose storing data temporarily in a disk cache or a work
optical disk drive 7 when an operation is executed the
prevents the data disk from inputting and outputting data to
the optical disk drive 6. Satoh is concerned with
accomplishing a reduction in the number of accesses of the
data disk drive 6 by using cache memory 5 in the work optical
disk drive 7. However, Satoh is not concerned with the
problem of storing data temporarily because the data disks are
not available because an operation is underway that prevents
the data disks from inputting and outputting data.
