Beschreibung
Zusammenfassung:	Limited play optical discs (LPOD's) are optical discs readable by a reading device for a limited period of time. After removal from it's packaging, an LPOD becomes unusable after a relatively short period of time. LPOD's can be provided with a limited shelf life by storing the LPOD's in a special package. The packaging includes a portion that controls the environment inside the package until a preset period of time passes, at which point reading-inhibit action of a material in the optical disc is allowed to go forward, which causes the disc to become unreadable. Hence, once the product exceeds its shelf life, it becomes unusable regardless of whether or not the package has been opened.
