An information encoding method in which, if desired to reproduce an information recording medium recorded in accordance with an encoding method for a new standard by a reproducing device adapted for coping with the encoding method for an old standard, the user is apprised 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 message information in addresses 200000 to 239999 is encoded simultaneously. The message information has been encoded in accordance with the encoding method for the old standard and which can be reproduced by the reproducing device adapted for coping with the encoding method for the old standard.
