Methods for treating spinal pathologies, and more specifically methods for treating articulating surfaces of facet joints. In some embodiments, an apparatus that includes a server, a service for a limited resource residing on the server, and a pool of workers for the service that execute service requests from a client in a distributed object network system is provided. After the time interval, the heating power is reduced, and the spiral servo tracks are written to the disk. In the first bus transmission mode, payload write data is to be sent to the slave device via the first channel or the third channel.
