Data converter, information recorder, and error detector
A data converter includes: an input module to which a first data series is input, the first data series having a first data sequence and a first error detection code corresponding to a remainder of division of the first data sequence by a predetermined polynomial; a conversion module converting the first data sequence into a second data sequence by processing including one of insertion, exchange, and inversion of a bit or a bit sequence, and exclusive-OR with a predetermined bit or bit sequence; a processing bit sequence generation module generating a processing bit sequence corresponding to the processing; and a code generation module generating a second error detection code corresponding to the second data sequence based on an exclusive-OR of the generated processing bit sequence and the first error detection code.
