Claim 22:
23. A data storage device comprising:
a first actuator assembly associated with a host-addressable first logical unit and configured to operate on a corresponding first set of disk media surfaces;
a second actuator assembly associated with a host-addressable second logical unit and configured to operate on a corresponding second set of disk media surfaces greater than the first set; and
a controller configured to:
receive an input/output (TO) operation request addressed to the first logical unit,
send a command to the second actuator assembly to execute at least a portion of the TO operation at a parasitic portion of the second set of disk media surfaces assigned to the first logical unit associated with the first actuator assembly, and
in response to the second actuator assembly executing the portion of the TO operation at the parasitic portion of the second set of disk media surfaces, returning a response to the TO operation request which is identified as from the first logical unit.
