First Claim
Patent Images
1. An optically altered optical disc comprising:
- a reflective content layer for storing content; and
an additional layer on which the reflective content layer is disposed, wherein said additional layer comprises a material which has a first optical transmissivity associated with light having a wavelength between about 400 nm and about 410 nm and has a second optical transmissivity associated with light having a wavelength of about 635 nm, wherein the first optical transmissivity is greater than the second optical transmissivity.
