Abstract

PURPOSE: To prevent the increment of the access time regardless of the double writing by carrying out the double writing or the like to the same tracks on both surfaces of the disk with a distance of the fixed sector secured.
CONSTITUTION: The continuous access is possible for the writing data even in case the data is written doubly, by writing the data within range Ai of track ti of the surface of the disk and also giving the double writing or the like to the data within range A'i opposite to the rotary direction separated by sector l which is larger than the sum of the scale of the block unit to be written into track ti on the back of the disk by one access and the number of blocks required for the period from end of the writing to the next writing. As a result, the increment can be avoided to the access time regardless of the double writing.
