<p>A method of recording data (Dd) on a recording medium (OD) such as a unloadable optical disk. In recording the recording data (Dd) on the recording medium (OD), recorded are device specifying data for specifying a recording/reproducing device (1) allowed to read the recording data (Dd) (e.g., a serial No. data (Ds) on the corresponding recording/reproducing device (1), or authentication program data (DPS) containing the serial No. data (Ds)) and a judging program which is read by the recording/reproducing device (1) before the read of the recording data (Dd) recorded on the recording medium (OD) and adapted for judging the coincidence between the recording/reproducing device (1) and the recording/reproducing device (1) specified according to the recorded device specifying data.</p> |
