Claim 18:
19. One or more processing devices comprising:
means for assigning one or more logical tracks to physical tracks of one or more disk surfaces such that a respective logical track of the logical tracks is assigned to comprise:
at least a portion of sectors of at least a primary physical track; and
at least a portion of sectors of at least a donor physical track of the physical tracks or sectors of a non-volatile memory storage, and the donor physical track donating fractions of its track as logical blocks to the respective logical track that includes sectors from the primary physical track,
wherein, to compensate for decreasing sectors per track at decreasing diameters of one or more disks, a logical track comprising sectors of a primary physical track having a shorter diameter has more donor track logical blocks, relative to a logical track comprising sectors of a primary physical track having a longer diameter; and

means for performing a data access operation with at least one of the logical tracks.
