PURPOSE:To raise the processing rate, by writing a data from one data buffer to a disk in which an object sector has been detected at first, and also writing the same data from the other data buffer to a disk in which said sector has been detected later. CONSTITUTION:In a magnetic disk control device which is provided with plural data buffers 1, 2 for temporarily storing an input data, and records the same data repeatedly in plural disks 7, 8, when an object sector is detected at first by the disk 7, a write priority rank deciding circuit 5 controls a transfer controlling circuit 3, and transfers a data of the data buffer 1 to the disk 7. Also, as soon as access of the other disk 8 ends, a data recorded in the data buffer 2 is transferred to the disk 8, too. In this way, when a data from one data buffer is being transferred, the other data buffer can be shifted to the next operation, therefore, the processing efficiency is raised. |
