发明名称 METHOD AND SYSTEM FOR MEDIA DISC LOSS PREVENTION
摘要 An apparatus, system and method discourage theft of a media disc. The media disc has a central aperture and is retained within a media disc case by an inner spindle that extends through the central aperture. A pin is insertable through the inner spindle. A locking clutch is operable to engage the pin. When engaged, the locking clutch secures the media disc upon the inner spindle and prevents the media disc from being removed from the inner spindle. A liquid-dispensing container is positioned between the pin and the media disc such that when a force is exerted upon the media disc to attempt to remove the disc from the inner spindle when the locking clutch is engaged, the liquid-dispensing container releases a liquid which renders the media disc unreadable.
