Multi-access data storage device with equalization of data rate

A method comprising:

• defining bins of tracks for each of different pluralities of tracks on disk surfaces in a disk drive, wherein respective ones of the different pluralities of tracks are associated with respective ones of an odd number of actuator assemblies in the disk drive;
• defining permutations of respective ones of the bins of tracks;
• and
• performing a read operation by concurrently reading data from at least one track in each of the different pluralities of tracks according to one of the permutations,
• wherein the defining the bins of tracks, the defining the permutations, and the performing the read operation are performed by one or more processing devices individually or in combination.

One or more processing devices, individually or in combination, comprising:

• means for performing a read operation in a disk drive by concurrently reading first data from a first band of tracks on one or more disk surfaces using a first head and second data from a second band of tracks on the one or more disk surfaces using a second head;
• means for moving the first head in a first radial direction of the one or more disk surfaces and the second head in a second radial direction of the one or more disk surfaces opposite the first radial direction during the read operation;
• and
• means for combining the first data and the second data into a digital output of the read operation;
• wherein the one or more disk surfaces are on one or more disks in the disk drive comprising two or more actuator mechanisms.
