发明名称 MODULATION APPARATUS, MODULATION METHOD, MODULATION PROGRAM AND MODULATION-PROGRAM RECORDING MEDIUM
摘要 A modulation device, a method thereof, a program, and a recording medium are provided to perform a DSV(Digital Sum Value) control operation surely when adopting an even-odd-characteristic retention violating change pattern. A modulation device(1) comprises a first change unit, a second change unit, and a selection unit. The first change unit changes a portion which is corresponded to a first data pattern of controlled data into a first code pattern according to the first data pattern formed with an even-odd-characteristic retention pattern, and a first table corresponding the first code pattern. The second change unit switches the portion which is corresponded to a second data pattern for the controlled data, into a second code pattern according to the second data pattern formed by an even-odd-characteristic violating pattern, and a second table corresponding the second code pattern. The selection unit selects one of the first and second code patterns to prevent the second code pattern from being changed when a DSV control bit is inserted into the controlled data. In a program thereof, one of the first and second code patterns is selected to prevent changes of the second code pattern when inserting the DSV control bit into the controlled data.
