Panasonic develops 100GB Blu-ray disc suitable for archiving

According to a report over at Tech-On, Panasonic has announced a 4 layer Blu-ray recordable disc, capable of holding 100 gigabytes of data. Not only that, they think if you had means, you could actually play it back 100 years from now!

Te-O-Pd film is an inorganic material, which Matsushita considers the cornerstone of its multilayer technology focusing on the material's high transmittance that makes it easy to increase the number of layers and low solubility that gives minor impact to the environment. In Te-O-Pd, substance transmittance, crystallization speed and durability depend on a composition ratio of these three elements. Matsushita said it discovered a ratio that realizes "100-year durability" (a company spokesperson), while achieving transmittance needed to create a four-layer disc and fast crystallization required for 2x writing speed.

Whereas it's great to be able and store such large
amounts of data upon a single small disc. It is also critical to make sure that data is retrievable at a later date. So, Panasonic is doing some good work here, making such stable media. The medias lack of sensitivity to moisture is a definate plus. Certainly, no one will be using such discs in the next century, but at least you can be reasonably confident, that with proper storage, your precious data will be there when you need it in the near future.

There is no time frame as of yet, to indicate an availability for this media or even pricing. However, it is aimed at archival use. More information on the discs performance can be found by visiting Tech On.
