摘要

PROBLEM TO BE SOLVED: To prohibit the formation of duplication of contents information in a large quantity in a short time. SOLUTION: When the musical pieces of a CD 100 are dubbed, the TOC information or music information of the CD 100 subjected to high-speed dubbing is stored as dubbing prohibition information to a RAM 90c and a non-volatile memory 95. The prohibition time information is also stored in combination. The prohibition time information stored in the RAM 90c is successively updated together with the lapse of time and the dubbing prohibition information elapsing the effective period of the prohibition time information is deleted from the RAM 90c and the memory 95. The high-speed dubbing processing of the second time is prohibited in accordance with the dubbing prohibition information stored in the RAM 90c. The information of the memory 95 is updated by using the information of the RAM 90c at every lapse of the prescribed period. When the information stored in the RAM 90c is lost, the information of the memory 95 is copied to the RAM 90c and the prohibition operation of the high-speed dubbing processing of the second time is carried out.
