PROBLEM TO BE SOLVED: To provide a data transfer control apparatus and method therefor capable of performing an effective data transfer. SOLUTION: When a conflict occurs between the data transfer from a RAM 102 to hard disks 108, 109 by a DMAC 1 (111), and the data transfer from the hard disk 109 to the RAM 102 by the DMAC 2 (110), an arbiter 116 controls the data transfer of the DMAC 1 (111) and the DMAC 2 (110) on the basis of a predetermined priority information, thereby reducing movement of head position when accessing to the hard disks.
