摘要
An apparatus is provided for surface-based data mapping for a disk drive system and a method of operation in which adjacent data tracks on the data storage surfaces of a disk drive are grouped into data track sets and data track sets on different data storage surfaces are grouped into bunches. The bunches are used to determine how to perform the logical to physical data layout mapping inside the disk drive. A disk drive controller controls disk read/write heads and provides a data layout mapping that maps logically adjacent data blocks to a data track, then to an adjacent data track radially along the same surface in a data track set in a bunch, and then to a different data track in a different data track set in the bunch.
