ABSTRACT:
Data units on a data storage medium include a control field. In one example embodiment, a control block specifies the control action determined by the state of one or more bits in the control field. By using a control block to specify the action of one or more bits in the control field, the action controlled by the data in the control field can be changed to accommodate future needs.
