Abstract:
A data modulation apparatus includes: insertion means for inserting information bits into data at a predetermined interval; conversion means for converting the data into which the information bits are inserted into an RLL code based on a modulation table that has a variable-length conversion rule; setting means for setting a control section that is used for calculating a value of the information bit; and determination means for determining the value of the information bit inserted into the control section that is different from a calculation target by calculating the code of the control section.
