A method of mapping logical track numbers to a collection of physical
tracks on at least two disk surfaces within a disk drive. The method
further includes accessing logical tracks at assigned physical tracks.
The invention includes making disk drives using the mapping of logical
tracks to physical tracks and those disk drives as a product of that
manufacturing process. The invention also includes program systems
implementing the mapping of logical tracks to physical tracks within the
disk drive and disk drives implementing the method of assigning logical
tracks to physical tracks and/or accessing logical tracks based upon the
physical track assignment.
