Claim 0:
1. A disk drive comprising:
a first actuator that controls an arm having a first head and extending over a first surface of a plurality of disk surfaces;
a second actuator that controls an arm having a second head and extending over a second surface of a plurality of disk surfaces other than the first surface; and
a controller configured to:
control the first actuator to start a first disk access operation; and
while the first actuator is moving in connection with the first disk access operation,
select a second disk access operation from a queue of operations to be performed by the second actuator,
determine that a disturbance time of the second disk access operation coincides with at least a portion of a critical time of the first disk access operation,
in response to determining that the disturbance time coincides with the at least a portion of the critical time, generate a modified second disk access operation that does not include the disturbance time that coincides with the at least a portion of the critical time of the first disk access operation,
select as an operation for execution either the modified second disk access operation or a third disk access operation from the queue of operations to be performed by the second actuator, and
execute the operation for execution.
