PURPOSE:To execute at a high speed write and read-out of a file to a disk by bringing a sector on the same track on the surface of a disk to an access divisionally, respectively, under a control of each head controller. CONSTITUTION:A control part in a disk 3' consists of a bus interface 15 serving as an interface to a system bus BUS connected to a CPU, and an IO processor (or DMAC) 16 for giving a control command to each head controller 171, 172 in accordance with each signal of an address ADR, a data DATA, and a control CNT which is read through its bus interface 15. The head controller 171 gives read RD, write WR and a control signal CNT1 to a head driver 131 in the disk 3'. Also, especially, this device is provided with a control means by which the sector on the same track on the disk surface 5 is brought to an access dividionally and simultaneously under a control of each head controller 171, 172. |
