<p>PURPOSE: A method and device is provide to prevent the disk type recording medium from being copied effectively by stopping the whatever process which are not recognised by the system. CONSTITUTION: A device and method comprises a video game machine(10), an optical disk(12), a disk access medium(14), a program operating controller(16), a protection code detector(24), a disk revitalizing controller(28), a main data buffer(30), an interface(32), a head operator(32), and a head drive controller(40). The video game machine(10) includes the disk access medium(14) which reads programs and data from the optical disk(12), and the program operating controller(16) which operates the program according to a certain process. The disk access medium(14) includes a spindle motor(18) which rotates the optical disk, a motor driving controller(20) which controls the spindle motor and an optical pick up(22) which outputs the radio frequency showing the read data which are optically read from the optical disk.</p> |
