System for encoding linear constraints and modulation constraints from product code That code is SOLVED] coupling is imposed, the data to be recorded in the medium, method, and computer program. First array of [MEANS FOR SOLVING PROBLEMS] uncoded user data is generated. The modulation coding to impose modulating the first constraint, that is, the array is converted to the second array, the second array, each row is given in the column of each of the interleaved data in a modulated data is converted into the third array with empty position. C2 parity bytes are computed for at least some of the empty position of the array of the third, the fourth array is generated. C1 parity symbols in each row is calculated, and generates the first array 5. Modulation second constraint is imposed on each of the C1 parity symbols in each row of the array of fifth to generate an array of 6. Rows of the array of the sixth, is combined with the synch field and a header for recording on a recording medium. [Selection Figure 7
