ABSTRACT:
A method is disclosed for selecting a format for a disk surface of a disk drive, the disk drive comprising the disk surface, and a head actuated over the disk surface. A first TPI is selected for the disk surface, and then evaluated to determine whether it is compatible with a first target capacity. If the first TPI is not compatible with the first target capacity, then a second TPI is selected for the disk surface wherein the second TPI is less than the first TPI.
