Claim 13:
14. A data storage device, comprising:
one or more disks;
at least one actuator mechanism configured to position at least a first head proximate to a first disk surface among the one or more disks and a second head proximate to a second disk surface among the one or more disks, the second disk surface being different from the first disk surface; and
one or more processing devices, wherein the one or more processing devices are configured to:
assign one or more logical tracks to physical tracks of two or more of the disk surfaces such that a respective logical track of the logical tracks comprises:
at least a portion of sectors of a primary physical track of the physical tracks, the primary physical track being on the first disk surface; and
at least a portion of sectors of a donor physical track of the physical tracks, the donor physical track being on the second disk surface; and
perform, using the first head proximate to the first disk surface and the second head proximate to the second disk surface, a data access operation with at least one of the logical tracks,

wherein the one or more processing devices are further configured to assign the logical tracks to the physical tracks with different formatting in different portions of the disk surfaces.
