ABSTRACT:
An MTR encoder includes convolution units that perform convolution of input data using additional bits, MTR encoding units that MTR-encode data obtained by the convolution units, RDS calculating units and on-bit sequence checking units that calculate RDSs and counts the number of sequential on-bits of the data MTR-encoded by the MTR encoding units, respectively, and a selecting unit that selects optimum data based on the RDSs and the number of sequential on-bits.
