  • Method for treating an optical disc layer to improve adhesion properties
    Patent number: 7011877
    Abstract: A method of improving the ability of plastic layers of a multi-layered optical disc to bond to adhesive materials includes exposing the plastic layers to a plurality of ions. In one embodiment, one side of a plastic layer of a multi-layered optical disc is exposed to a plurality of non-reactive ions, an adhesive material is applied to the side of the plastic layer that was exposed to the plurality of ions, and a second layer of the optical disc is secured to the adhesive material. In another embodiment, a plurality of ions is formed by directing gas molecules through an electric field, and at least 25% of the width of the plastic layer of the multi-layered optical disc is exposed to the plurality of ions at about the same time. The plastic layer is positioned so that the ions contact the plastic layer while the ions still have a charge, and the disc is moved so that at least 25% of the surface of the plastic layer is exposed to the plurality of ions.
