Panasonic creates 100GB Blu-ray discs to last 100 years
 

Panasonic has developed a 4-layer, 100GB Blu-ray disc that it claims will last for 100 years by using a tellurium suboxide palladium-doped phase-change recording film, called Te-O-Pd. The film has a high transmittance and crystallization rate which allows them to layer it on without losing data quality.
