Abstract: There is provided a method and apparatus for sending an encoded signal between a host station and a client station in which the host station encodes data, encodes the error data resulting from that encoding process and generates user data. Thus, the host station generates three types of data and it accords different priorities to those three data types. The first type of data, the encoded original data is accorded the highest priority and is guaranteed delivery to a client station. Thus, a minimum signal quality is guaranteed at the client end. The second type of data, user data, is accorded a lower priority and will be delivered to the client station if there is available bandwidth once the encoded original data has been successfully delivered. The third type of data, encoded error data is accorded the lowest priority and is only delivered to the client station if there is available bandwidth once the encoded original data and the user data have been delivered.

Abstract: A disk drive motor control system which dynamically varies the speed of the motor in accordance with the desired data transfer rate is provided. This is accomplished by monitoring the transfer rate and lowering the speed when the transfer rate decreases and then raising the speed when the transfer rate increases. Hysteresis is preferably built-in so that rapid oscillations between the two speeds do not occur.
