Abstract: 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.

Abstract: One implementation of the disclosed technology involves detecting a transition in a signal received via one of a first indexed input and a second indexed input. The transition defines a first symbol having a symbol value. This implementation further involves outputting the first symbol in response to detection of a transition. The symbol value of the first symbol is designated by the index of the indexed input upon which the transition is detected.
