ABSTRACT:
A modulator includes a replacement processing unit which replaces a part of main information code-converted in a main information converter with specific information code-converted in a specific information converter and a direct-current component suppress processing unit which performs direct-current component suppress processing for the main information which has undergone the replacement processing in the replacement processing unit. The direct-current component suppress processing can be performed for the main information after the replacement processing of the main information with the specific information to prevent deterioration in direct-current component suppress characteristics due to the replacement processing.
