A recording medium and a recording apparatus for storing manufacturer information for supporting specific functions for each manufacturer and a method therefor. A reproducing apparatus for reproducing manufacturer information for supporting specific functions and a method therefor is also provided. If a recording apparatus modifies the contents of the recording medium, then it should record its manufacturer's identification code. A recording apparatus/reproducing apparatus should check the identification code on the recording medium before using its own manufacture information item for some specific function. Also, it is possible to reduce the time required to determine whether the manufacturer information items are effective. |

DETAILED DESCRIPTION It is a first object of the present invention to provide a recording medium for storing manufacturer information for a specific function of recorders/players of different manufacturers.
It is a second object of the present invention to provide a recording medium for storing identification information of the manufacturer of a recorder/editor which last performed recording/deleting on the recording medium.
It is a third object of the present invention to provide a recorder/editor for and method of storing on a recording medium manufacturer information for a specific function of the recorder/editor of each different manufacturer.
It is a fourth object of the present invention to provide a recorder/editor for and a method of storing on a recording medium identification information of a manufacturer of the recorder/editor which performs recording/deleting.
It is a fifth object of the present invention to provide a recorder/player for and method of using the manufacturer information stored on the recording medium for the specific function of the recorders/players of each different manufacturer.
It is a sixth object of the present invention to provide a recorder/player for and method of checking whether the identification information of the manufacturer of a recorder/editor which last performs recording/deleting on the recording medium is the same as the identification information of the manufacturer of the recorder/player to determine whether or not the manufacturer information is effective.
That is, if the respective identification information is the same, then the manufacturer information item is effective.
If not, the manufacturer information item may be not effective, thus requiring complete verification.
The above objects are achieved in accordance with the present invention with a rewritable recording medium to store audio/video (A/V) contents, including formatted information for the A/V contents, and manufacturer information to support the manufacturer's specific function, wherein the manufacturer information comprises an identification code of a manufacturer of a recording apparatus that last modified the content of the recording medium
