Publication number: 20090016187Abstract: A secure optical data disc comprising an electronic article surveillance tag embedded within a layered disc structure comprising first and second substrates is disclosed. The tag is placed within a non-readable zone (i.e., one that does not have data tracks) of the secure disc. To improve signal quality of the tag, the reflective metal layer thickness is minimized and discontinuities are introduced on the reflective metal layer. A first discontinuity separates a data track region of the disc from a mirror/ID band region. A second, radial discontinuity opens the mirror/ID band ring.Type: ApplicationFiled: March 5, 2007Publication date: January 15, 2009Applicant: Vidco, Inc.Inventor: Joel Douglas Bigley

Patent number: 7411893Abstract: A secure optical data disc comprising an electronic article surveillance tag embedded within a layered disc structure comprising first and second substrates is disclosed. The tag is placed within a non-readable zone (i.e., one that does not have data tracks) of the secure disc. Layer-wise, the tag is either sandwiched between the two substrates or alternatively embedded within one of the two substrates. In the case where the tag is sandwiched between first and second substrates, a bonding layer occupies a space radially outward from the tag. The bonding layer holds the first and second substrates together thereby forming the secure disc.Type: GrantFiled: February 26, 2007Date of Patent: August 12, 2008Assignee: Vidco, Inc.Inventor: Joel Douglas Bigley

Publication number: 20070274196Abstract: A secure optical information disc comprising an electronic article surveillance tag embedded within a recess of a substrate of the disc structure is disclosed. The tag is placed within the recess such that it does not interfere with reading optically encoded information using a laser beam pick-up assembly such as those used to read DVD, CD, HD and Blu-Ray (BD) discs. The tag is placed within a recess having either no inner wall or an inclined wall.Type: ApplicationFiled: February 13, 2007Publication date: November 29, 2007Applicant: Vidco, Inc.Inventor: Joel Bigley
