What is the largest capacity of any optical disk (cd, dvd, blu ray, etc..)?

Question

Blu Ray holds 25 GB 1 layer and 50 GB 2 layer, are they're any bigger?? And how big?

Answer 1

Teradisc will currently hold 1000GB on a DVD sized disc. There just now pushing there 600GB to consumer markets. Blu-ray has nothing compared to this technology.

They been perfecting this for the last 6 years. Filed 21 patents and have the backing from Japanese companies.

Answer 2

The only approved discs for BD-Video are BD25 and BD50 discs.

In order for them to use a bigger disc for movies, they'd have to ensure that it could work with all current models of Blu-ray Disc players.

There's not much reason for a disc bigger than a BD50 right now.

For PC usage it's a different matter altogether. You should start seeing BD100 and BD200 BD-R's showing up within the next year or so.

Answer 3

Manufacturers of blu-ray discs have supposedly created a 10 and 20 layer blu-ray disc that would hold 250GB and 500GB respectively.  I've heard that supposedly a blu-ray disc holding up to 1TB (1000GB) could be possible.

Will we ever see such a thing?  Who knows?  Movies work fine on single layer blu-rays for now.  If they ever decide to start selling entire TV seasons on a single disc (yes please!) we might see higher capacity discs but I suspect we'll only see these over in the computer area, for data archival purposes (backups) - and they'll cost a ridiculous amount of money.
