Method and apparatus that modifies seek parameter to remediate cross-actuator interference

A system comprising:

• a first actuator that drives a first head;
• a second actuator different from the first actuator that drives a second head different from the first head;
• and
• a controller coupled to the first and second actuators and configured to:
• set at least one criterion that indicates a likelihood of cross-actuator interference from the second actuator that impacts the first;
• modify a seek parameter of the second actuator responsive to detecting the at least one criterion affecting the first head;
• and
• verify that the modification of the seek parameter improves performance of the first head according to the at least one criterion.

An apparatus comprising:

• interface circuitry coupled to first and second actuators that drive respective first and second heads that read one or more disks;
• and
• a controller coupled to the interface circuitry and operable to:
• set at least one criterion that indicates a likelihood of cross-actuator interference from the second actuator that impacts the first;
• modify a seek parameter of the second actuator responsive to detecting the at least one criterion affecting the first head;
• and
• verify that the modification of the seek parameter improves performance of the first head according to the at least one criterion.
