ABSTRACT:
A hard disk format is disclosed which sequentially arranges a number of different sector types, each having a different format, into frames which are repeated around the tracks of a magnetic disk. The sector types and frame arrangements are chosen so that servo bursts are optimally located around the tracks of a magnetic disk. The sectors of the magnetic disk may have servo bursts located virtually anywhere within each sector. A magnetic disk controller used in conjunction with the magnetic disk processes each sector during reading from or writing to a sector according to whether or not the sector contains a servo burst.
