Information distribution method, information distribution system and information distribution apparatus

摘要

The present invention introduces an information distribution method capable of making an information distribution business for reliably authenticating a recording medium and distributing information in a prepaid manner. For this end, ID information recorded in a read-only area is read out from a disc-shaped recording medium having a read-only area and a recording and/or reading area. Judgment (or decision) is made whether or not information distribution to the recording medium is permitted based on the read-out ID information. The signal information distributed as a result of the judgment is recorded in the recording and/or reading area of the recording medium. The recording and/or reading area of the recording medium is rewritable. In case of reading the ID information out of the read-only area of the recording medium, erasing of recorded information for the recording and/or reading area is performed at the recording position for the ID information before reading the ID information.
