<p>A disposal method of a waste optical disc is useful when a substrate material is collected from the disc. A space is created between a recording layer and a reflective layer between both of which there exists the smallest mutual adhesion by cutting a surface of a protective layer side of an optical disc. Then, the reflective layer and the protective layer are peeled off and removed from the optical disc by introducing air into the space therebetween. Then, the recorded layer remaining on a substrate layer can be removed by cutting.</p> |
