Claim 12:
13. 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 respective logical track is further assigned to at least a second, virtual donor track in a non-volatile memory storage.
