limit

[univ]

I don't know anything about physics.
Now I know the difference between "blue" and "red".
Wheter "blue" is the limit or not, my question is: shouldn't there be a limit in bettering things sooner or later? I mean when "the theoretical"- and "the practical"-solution meet somewhere. In other words: "resolution + quantity" has to reach a limit.
Does anyone want a solution suggested by some people which means that every music and film is saved in one and the same disc? I really don't like that solution.

Not sure about limits. Though there's a holograhic disc in development with 1,024 GC capacity, (1 Terabyte). Then some way in the future there's a disc using nano technology with 100,000 TB or more. Still, I would suggest a 1TB discs would easily be sufficient for hi-def resolutions of 1920/1080p.

As for a single format, I think it makes sense. Why do we need cd, dvd, dvdA, SACD. Why can't we have the one disc that plays music, video etc? :?:

One and only one single format is what I advocate.

The question was about the limit: "resolution + quantity (size)". It's wonderful to have a long movie on one and the same disc with best resolution.

Some people say that in the future you don't have to buy anything, except downloading whatever you want into a large harddisk. (Maybe you will not even have any bookcases in your livingroom either. Every book is published as an e-book...)

I don't like that kind of future maybe because I am conservative. But somehow all this format-war sounds a bit strange if you compare the 50 Gb DVD with a 1 TB harddisk. The future has in one sense already started. You can already download many things directly from music- and filmcompanies...
