DISKLIKE RECORDING MEDIA, A METHOD FOR DETECTING FORGED DISKS, AN ANTI-FORGERY SYSTEM FOR PERFORMING A TRUE-FALSE JUDGEMENT BASED ON INFORMATION COLLECTED FROM THE RECORDING MEDIA, AND A MANUFACTURING APPARATUS FOR RECORDING INFORMATION IN THE DISKS

   
   

A recording medium includes first information selected from a plurality of information patterns and second information selected from another plurality of information patterns for the true-false judgement. A true-false judging device performs a statistic analysis when any coincidence is found between the readout combination of the first and second information and registered combination patterns, to identify an inspected recording medium as a forged product based on the result of the statistic analysis.
