To minimize the time and resources typically associated with collision detection in a single channel communications system, this invention provides a method and apparatus for a collision based protocol that assures that one device in the system always wins a collision conflict. A device in accordance with this invention that is assured of always winning a collision conflict need not contain a collision detector, nor the storage resources typically used to buffer the effects of a collision. The device is also always assured of continuous transmission access once its transmission begins. This continuous transmission access is particularly well suited for high speed data access devices such as magnetic disks, laser discs, and the like, that access data continually as the disk passes by their read heads. |
