Abstract

PURPOSE: To avoid the timing limit, by suppressing the movement of heat at write- in to alternate recording area to a minimum value, through the provision of a plurality of magnetic disc devices and preparing the alternate recording area in place of failure area on other devices.
CONSTITUTION: A plurality of magnetic disc devices 11-0W11-3 are provided, and the alternate recording area in place of the failure areas AWD are provided respectively on A'WD'. For example, via the data buffers 23-0, 23-1, write-in is made from the location of X1 of the device 11-0 and if it reaches the failed location A', it is written in the alternate recording location A' of the device 11-2. At the device 11-2, the head is at the location of X2, the movement of head is for one cylinder's share at maximum. Further, when the location of failed location C is written in C', since the data recording of 11-0 is finished, the head is at the location of Z1 and the movement of head can be less.
