An optical recording reproducing apparatus comprising:
- a catalyst layer formed on an objective lens of the optical recording reproducing apparatus, an optical disc and a surface of a slider which is formed near the optical disc;
- and
- a light irradiation unit for irradiating light on the catalyst layer.
An optical recording reproducing apparatus comprising:
- a catalyst layer formed on a surface of a slider which is formed near a surface of an optical disc and where an objective lens of the apparatus is mounted, for removing contamination material, wherein the catalyst layer is formed on the optical disc and the objective lens;
- and
- a light irradiation unit for irradiating light on the catalyst layer, wherein the light irradiation unit irradiates the light on the catalyst layer during reproducing information of the optical disc or recording information in the optical disc.
