ABSTRACT:
Registers are inclined to react to any interference as follows: if any one stage inverts, the entire register inverts. In one embodiment, one additional bit is associated with the register, which bit is used to indicate that interference has occurred. Registers may then be inverted to their original form or may, by equating the meaning of the inverted form of the information contents of registers to the original form, ignore disturbance(s) caused by interference. Information media such as magnetic or optical discs for storage of such information thereon are also disclosed. The invention brings order to information failures caused by interference and thus is able to use such failures as opposed to other approaches which fight such failures. The invention avoids the need to keep track of original and inverted forms of information, independent of interference.
