Abstract
An erasable and re-writable disc label system includes a release layer and a plastic film disposed over the release layer with one side of the plastic film releasably adhered to the release layer with an acrylic adhesive for enabling permanent application of the plastic film to an optical disc without degradation of disc optic properties. The plastic film is formed from material enabling the plastic film and adhesive to be removed from the release layer while maintaining plastic film initial shape, size and symmetry in order to prevent imbalancing of the optical disc upon application thereto. A coating is provided on a second side of the plastic film for enabling non-indelible marking thereon with a marker pen and subsequent erasure of the marking.
