Abstract
The present invention provides an optical disc recycling method for recycling optical disc including at least a light transmitting substrate and at least one metal layer containing a metal such as aluminium and gold provided on one side of the substrate. An adhesive member is adhered to the substrate side having the metal containing layer and the adhesive member adhered to the metal containing layer on the substrate is peeled off so as to separate the metal containing layer from the substrate.
Claims22
An optical disc recycling method for recycling an optical disc including at least a light transmitting substrate and a layer containing a metal provided on at least one side of said substrate, said method comprising:
- a step of placing an adhesive member on the substrate side having said metal containing layer;
- and
- a step of peeling off said adhesive member adhered to said metal containing layer from said substrate so as to separate said metal containing layer from said substrate.
An optical disc recycling method for recycling an optical disc including at least a substrate made from a light transmitting synthetic resin, at least one metal containing layer provided on one side of said substrate, and a protection layer formed from a synthetic resin so as to protect said metal containing layer, said method comprising:
- a step of placing an adhesive member onto the substrate side having said metal containing layer;
- and
- a step of peeling off said adhesive member adhered to said substrate side having said metal containing layer, so as to separate said protection layer and said metal containing layer from said substrate.
