• recording and holding AV data supported by a copyright protection system permitting multiple times dubbing in a recording medium provided to the data recording apparatus;
• performing dubbing or moving of AV data between at least one storage medium which is portable with a capacity capable of storing AV data, and the recording medium, or between the storage medium and another storage medium different from the storage medium;
• managing dubbing management information for the AV data, the information including the permitted number of times of dubbing which is assigned in accordance with the copyright protection system;
• and
• determining whether the storage medium is rewritable or non-rewritable based on a media type of the storage medium which is a destination of dubbing or moving of the AV data in said performing dubbing or moving,
• wherein in said managing, the dubbing management information corresponding to the AV data according to the determination result is updated when the AV data is moved from said record holding unit to the storage medium in said performing dubbing or moving of AV data, and
• in the case where it is determined in said determining that the storage medium is rewritable based on the media type of the storage medium, the dubbing management information is updated in said managing according to the determination result by maintaining the value of the permitted number of times of dubbing corresponding to the AV data while the move is performed in said performing dubbing or moving of AV data.

A non-transitory computer-readable medium having a program stored thereon for executing data recording in a data recording apparatus, said program causing a computer to execute:

• recording and holding AV data supported by a copyright protection system permitting multiple times dubbing in a recording medium provided to the data recording apparatus;
• performing dubbing or moving of AV data between at least one storage medium which is portable with a capacity capable of storing AV data, and the recording medium, or between the storage medium and another storage medium different from the storage medium;
• managing dubbing management information for the AV data, the information including the permitted number of times of dubbing which is assigned in accordance with the copyright protection system;
• and
• determining whether a storage medium is rewritable or non-rewritable based on the media type of the storage medium which is a destination of dubbing or moving of the AV data performed in said performing dubbing or moving,
• wherein in said managing dubbing management information, the dubbing management information corresponding to the AV data according to the determination result is updated when the AV data is moved from said record holding unit to the storage medium in said performing dubbing or moving of AV data, and
• in the case where it is determined in said determining that the storage medium is rewritable based on the media type of the storage medium, the dubbing management information is updated in said managing according to the determination result by maintaining the value of the permitted number of times of dubbing corresponding to the AV data while the move is performed in said performing dubbing or moving of AV data.
