Abstract
PURPOSE: To simplify the error correction circuit and also increase the quality of the reproduced picture or sound, by storing the read information into several memories and then averaging the information through a signal averaging circuit.
CONSTITUTION: Each of the information supplied from the reading parts 1W3 is stored in each of the memories 1W3 and then led to the averaging circuit 19 to be averaged. The SN is improved greatly for the output of the circuit 19 to reduce the reading mistake to a great extent. As a result, the quality can be increased for the reproduced picture or sound although the constitution is simplified for the error correct correction circuit.
