PURPOSE:To copy an optical information recording disk easily and at low cost, by placing oppositely a metallic original disk in which information has been recorded by through-holes, on a material of a disk to be copied, and transferring an information image by injecting ink to the material of the disk to be copied through the through-holes, and the like. CONSTITUTION:An information bit 9 is formed by irradiating laser beam 6 from an optical system 7 to a metallic film 2 formed on a glass substrate 1, through a lens 8, by which an optical information recording disk 3 is prepared. A metallic original disk 14 having through-holes 15 is prepared by thickly plating only the film 2 except this bit 9. The original disk 14 is fixed to a frame 17 having a stepped part 18 with a stopper 21, and a rerecording disk 23 is mounted to the frame 17 leaving a space against the original disk 14. Subsequently, ink 22 is injected from the through-holes 15 and is made to adhere onto the rerecording disk by a pressing from a leading-in port 19 of an ink store chamber of the frame 17, by a pressure adjusting means 20. Subsequently, injection of ink is stopped by reducing pressure by the means 20, and after that the disk 23 is detached. In this way, since the laser beam 6 is absrobed by the adhering part of the ink 22 and reflected beam is weakedned, the recording information is reproduced from the rerecording disk 23 by the presence or absence of the ink 22. |
