摘要 |
A magnetic head accesses sectors of one track in the order starting with a sector where the magnetic head is put into an on-track state. A seek start timing is reliably determined by accessing on a track by track basis with an uncertain process of a read-ahead operation eliminated. A search time is eliminated by accessing any sector within one track. As a result, the number of seeks is minimized and access time is reduced. A sector format is used to perform an access operation on a track by track basis. In this arrangement, each of seek time and search time is reduced during a random access time and a data transmission speed of a disk drive is assured.
