[0026] A method of adding an optical disc information layer includes: ① coating a coating layer on the surface of the substrate 7; ② accurately positioning the substrate 7 coated with a coating layer on the substrate tray 5; ③ The substrate tray 5 is placed on a mechanical transmission device; ④ The mechanical transmission device is used to transfer the substrate 7 with the coating layer to a designated position; ⑤ A closed space is created at the designated position to make the substrate with the coating layer 7 is located in the sealed space at the designated position, so that the substrate 7 with the coating layer is in the closed space; ⑥ In the sealed space, a master disk 22 is used to coaxially cover the substrate 7 with the coating layer from above. On the coating layer; ⑦Under the substrate 7 with the coating layer, irradiate the coating layer with an ultraviolet lamp 2 to cure the coating layer, and the information of the master disk 22 is copied to the coating layer of t...
