ABSTRACT:
In a spin-up process in a disk drive, the values of a PMA counter and a TOC counter are compared with each other with respect to a write-once disk. The PM counter is a adapted to count the number of disks in which information is written in a PMA region, among the disks from which information is theretofore read in the disk drive. The TOC counter is adapted to count the number of disks in which information is not written in the PMA region.
