Abstract
An information reproduction system that provides an apparatus for reproducing audio/video information from an information recording medium having a tape form for example and circumventing problems associated with illegal copies of information recording media. If a match is found between the contents of identification data information read from a memory fixed to a cassette incorporating a magnetic tape and the contents of individual key data information stored in an information storage memory, a controller causes an information reproducing block to reproduce main information from the magnetic tape.
