Claim 15:
16. A method of selecting and executing disk access commands in a disk drive that includes a first actuator that controls an arm having a first head and a second actuator that controls an arm having a second head, the method comprising:
controlling 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,
selecting a second disk access operation from a queue of operations to be performed by the second actuator,
determining 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, generating 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,
selecting 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
executing the operation for execution.
