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

Filed under: — By Aviran Mordo @ 10:48 pm

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.

Each of the four layers in the disc has a 25GB storage capacity totaling up to 100GB and are capable of a 2x writing speed. Te-O-Pd is inorganic and not-very-soluble, so when the discs finally do get tossed in a century or so, they won’t toxify the Earth too much.
