Abstract:

A method and system for laying out and accessing data in a disk drive system. The layout resides in a table in firmware of the disk drive system. The table includes multiple entries or rows, one corresponding to each different area in the disk media. The entry provides information about the range of block addresses in that area including the starting and end block address in the area, and information about the range of physical addresses including the head and the starting and ending cylinder number. A firmware routine finds the appropriate entry in the table and converts the block address to the physical address, or vice versa.
