Machine-Readable Optical Disc With Reading-Inhibit Agent
US Patent:
6343063, Jan 29, 2002
Filed:
Oct 20, 1999
Appl. No.:
09/421490
Inventors:
Philip E. Rollhaus - Chicago IL

Assignee:
SpectraDisc Corp. - Providence RI
International Classification:
G11B 370
US Classification:
369286
Abstract:
An optical disc having machine-readable, information-encoding features is provided with a barrier layer secured to the disc. This barrier layer is configured to prevent machine-reading of the features. A reading-inhibit agent, included in the disc and activated by removal of the barrier layer, is operative, once activated, to alter the disc to inhibit reading of the disc, after some period of time. Alternately, the barrier layer can be eliminated, and the reading-inhibit agent can be activated by initial reading of the disc, as for example by exposure to optical radiation associated with reading of the disc, or rotation of the disc.
