ABSTRACT:
An information encoding method encodes information on a recording medium in accordance with for a new standard. When decoded by a reproducing device adapted for coping with the encoding method for a old standard, the user is apprized of the fact that part of the recorded signals cannot be reproduced by a reproducing device adapted for coping only with the encoding method for the old standard. For encoding the information in accordance with the encoding method for the new standard, the user message information is encoded simultaneously. The user message information has been encoded in accordance with the encoding method for the old standard, which can be reproduced by the reproducing device adapted for coping with the encoding method for the old standard.
