PROBLEM TO BE SOLVED: To provide an encoder, decoder, and encoding method capable of encoding and decoding data with a small circuit. SOLUTION: A second input register 1112 and first input register 1111 are linked to each other and store consecutive input data. When zero run which violates G constraint is detected from the data stored in these two registers, data before and after G constraint violation are transferred by a zero run removal bus 1130 and synthesized in a temporary register 1150. Thus, by effectively using the mechanism of bus transfer, a circuit can be simplified, thereby realizing a small circuit. COPYRIGHT: (C)2007,JPO&INPIT
