Abstract
Methods and systems for content distribution are provided that include a broadcast transmitter for transmitting a signal that comprises content, a receiver for receiving the signal, and an optical disc recorder coupled to the receiver for recording the content to an optical disc, which may be an optically altered optical disc.
Claims41
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.
A method for forming an optically altered optical disc, the method comprising:
- providing a first disc layer, and
- disposing a reflective content layer on said first later,
- wherein said first disc 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.
An optically altered optical disc, comprising:
- a means for storing content;
- and
- a means for coating comprising 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;
- wherein said means for storing content is disposed on said means for coating.
