ABSTRACT:
A rate 2/5 (2,18,2) code especially suitable for use with a resonant coil overwrite technique for magneto-optical recording. Serial binary input data is converted to serial binary code data that satisfies a (2,18,2) constraint and is reconverted to the serial binary input data. An encoder receives two sequential input bits and a five-bit state vector derived from an immediately preceding encoding operation, and generates a five-bit codeword and a new five-bit state vector based on the two input bits and five-bit state vector. A decoder converts the binary code data into five-bit codewords, converts each five-bit codeword sequentially into a reassigned three-bit codeword representation, then collects sets of four adjacent three-bit codeword representations. Each reassigned codeword representation is converted to a two-bit output corresponding to a then current set of said four three-bit codeword representations, and successive two-bit outputs are reconverted into the serial binary data.
