摘要：
A position detection device, a position detection method, a position detection control device, a position detection control method, a position detection control program, an access authentication device, an access authentication method, an access authentication control device, an access authentication control method, an access authentication control program, an information storage device, and an optical disk are provided, all of which make it possible to prevent illegal copying of the information recorded in a recording medium.An information recording/playback device detects the position on an optical disk of an RFID tag provided to the optical disk, and writes the detected position on the optical disk of the RFID tag into the RFID tag as the position information.
