PURPOSE:To obtain an optical recording medium to which dirt and dust hardly apply and to prevent the occurrence of an error in writing or reading by a method wherein in the optical recording medium on which information can be written or read by a laser light, a layer containing a light transmitting particle having conductive properties is provided on the laser light incident surface of the optical recording medium. CONSTITUTION:As conductive light-transmitting fine particle, indium oxide can be exemplified. By adding, mixing, and stirring the conductive light- transmitting fine particle in an inactive organic solvent, such as a silane coupling agent, the silane coupling agent is adsorbed on the surface of the conductive light-transmitting fine particle, and the surface treatment is completed. The particle surface-treated with the silane coupling agent is uniformly mixed with a multifunctional-base acrylic material. This is applied on an optical disk substrate 2 and cured by an ultraviolet radiation or an electron beam. This organic protective film 5 is provided on the laser light incident surface of the optical disk. |
