The EZ-D disc contains a layer made of a modified form of Lexan. The new co-polymer degrades once exposed to air from transparent to opaque. The EZ-D would be supplied in an air-tight cover and once opened the layer would begin to react.
The intended market from the EZ-D is for short-term hire and promotional deals. Once unplayable the disc can be recycled or disposed. Able to be used in any standard DVD player the manufacturers hope it will succeed where other time-limited DVD technologies, such as DIVX, have failed. Test marketing will begin in August 2003.
