Abstract
A magnetic disk for a hard disk drive comprising a plurality of physical sector sizes is disclosed. The magnetic disk includes a first sector size area physically formatted according to a first physical sector size and a second sector size area physically formatted according to a second physical sector size different from the first sector size by a multiple of the first sector size wherein the second sector size can be presented externally as multiple sectors of said first sector size.
Claims19
A magnetic disk for a hard disk drive comprising:
- a first sector size area physically formatted according to a first physical sector size;
- and
- a second sector size area physically formatted according to a second physical sector size different from said first sector size by a multiple of said first sector size wherein said second sector size area comprises externally presented multiple separate sectors of said first sector size.
