Sequentially increase the speed to 20,000, 3,000, and 5,000 rpm for 5 seconds each. The coated substrate was baked at 80 ° C for 10 minutes' to form a dry and uniform optical recording layer. A silver reflective layer with a bond-killing thickness of about 100 nm is deposited on the recording layer by a metal-plating machine, and then a UV-curing resin (UV Lacquer) with a thickness of about 3,000 to 4,000 nm is spin-coated on the reflective layer. The above-mentioned resin layer is hardened by ultraviolet rays to form a complete recording medium. An optical disc recording device using a semiconductor laser optical head with a vibration wavelength of 780 nm was used to record the EFM modulation signal on the above-mentioned optical recording medium according to the machine's best linear speed and the best laser power. 20 was manufactured by the same method.
