I wonder, why not using one of those strange materials NASA, ESA and space agencies have develped and look to license ?
Why not using another format, not a disc, maybe a cilider or another shape ?
I really think if somebodyget really in to could develop something really stunning, maybe or surely big recording companies would not care and even wouldkill the format but who knows maybestarting in audiophilee circles could bea good start.
If there are now cranes and motors the size of a human hair I think many things are possible...
