Abstract
A marking device for marking optical discs in a non-destructive, tamper-proof manner for licensing and other purposes such as part of a digital content library service includes top and bottom structures coupled together by a hinge. The bottom structure is adapted with a mounting post in a recessed area defined by opposing curved ledges to hold an optical disc for marking. The top structure is adapted with a removable tool having an embossed symbol for impressing a mark on the held optical disc by applying pressure to the top structure when the device is in a closed position. The top structure is also adapted with perforations for alternatively or additionally injecting a permanent ink onto the optical disc so that a mark defined by the pattern of perforations may be placed on the optical disc.
