Abstract: A microprocessor 10 controls the access of head 6 to storage disk 2. The final sector in each track on a storage disk 2 is provided with final sector designating means 41. On reaching the final sector, an interrupt signal is applied to the microprocessor and the access to that track can be completed.

Abstract: JA9-89-009 DISK CONTROL APPARATUS A disk control apparatus for controlling head access to a multi-track disk includes a means for detecting final sectors in the disks and generating a final sector detection signal upon locating any final sector designating means provided in the respective final sectors of each of the tracks of the disk. The final sector designating means may be provided by merely reversing the bit value (e.g. 0 to 1) in an I.D. field.
