摘要

Contents are divided into a plurality of parts of the contents with a predetermined time interval, thereby to form a plurality of pieces of divided-contents information. For each piece of the divided-contents information, header information is generated which includes a pointer that shows a record starting position, permission flag information relating to watching or erasing of the contents, and password information for obtaining a permission of a decoding or an erasing. The plurality of pieces of divided-contents information and the corresponding plurality of pieces of header information are recorded onto the same recording medium. From this recording medium, it is possible to reproduce or erase the divided-contents information of which reproduction or erasing is permitted by the permission flag information, and the divided-contents information of which reproduction or erasing is prohibited by the permission flag information but for which the password of the contents and a user input password coincide with each other.
