Data storage drive with low-latency ports coupling multiple servo control processors
First and second servo control processors are coupled to respective first and second actuators that independently position first and second heads over one or more disks of a data storage drive. The first and second servo control processors are further coupled to first and second low-latency ports. F...

| description | First and second servo control processors are coupled to respective first and second actuators that independently position first and second heads over one or more disks of a data storage drive. The first and second servo control processors are further coupled to first and second low-latency ports. First and second unidirectional buses couple the first and second low-latency ports. The first and second unidirectional busses are operable to isochronously exchange servo positioning data between the first and second servo control processors. The first and second servo control processors each use the servo positioning data to compensate for movement caused by another of the first and second servo control processors. |
