The purpose of this work is to create a device for computer games, which uses the information carrier, allowing simple editing by the manufacturer and the impossibility of copying and editing by other firms without expenditures for elaboration and putting into production.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
