Classification: CPC G | IPC G

Claim 0:
1. 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 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 the 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
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.
