Abstract
A file control apparatus and a data transferring method that are capable of accessing data within a disk storage device at a much higher speed. The file control apparatus, when there arises a necessity for writing track data within a cache memory back to a disk storage device, writes a series of track data containing that piece of track data and to be written back to the consecutive tracks back to the disk storage device from within the cache memory and stores the effect that each piece of track data that has been written back is data requiring no necessity for the write-back process.
