ABSTRACT:
A data modulation apparatus for modulating data by run-length limited (1,7) modulation including constant data adding means for receiving input data and adding constant data after the input data, status data producing means for performing, in each modulation period, logical operations on at least part of the data output by the constant data adding means of each modulation period and the status data of the modulation period immediately before each modulation period to produce status data of each modulation period, and modulated data producing means for performing, in each modulation period, logical operations on the data output by the constant data adding means of each modulation period and the status data of the modulation period immediately before each modulation period to perform run-length limited (1,7) modulation and produce modulated data. Also, a data demodulation apparatus, run-length limited (1,7) modulated data recording apparatus, and a recording medium used with the same.
