<p>It is possible to provide an optical recording disc capable of reducing the read error occurrence ratio when a capacity of data within a predetermined range is recorded and to provide an optical recording disc capable of preventing unauthorized copying. In an optical recording disc (1) having a normalized predetermined recording capacity, the recording capacity is increased by up to 5% of the normalized recording capacity while maintaining the compatibility of normalized write and read. On an area of capacity exceeding the normalized predetermined recording capacity of the optical recording disc, a file concerning on automatic execution of the optical recording disc upon mounting on the disc drive is recorded. The file concerning the automatic execution is executed during the series of automatic execution when the optical recording disc is mounted on the disc drive.</p> |
