Cds+scratch proof glasses lens=:cool:

has anyone ever really thought about the amzing possibilities of making cds out of the same material as scratch proof glasses?

 

Not really man, cd's are plastic and aluminum, I don't think it would work out. Compact discs are already the most durable audio format, out of vinyl, tape, and vhs-tape, why would they need to be any better?

 

as durable as they are its not very...

 

Bullshit CD's are durable. I'm sooooo pissed because some of my favorite CD's are close to ruined. My problem isn't the scratches though, it's the top refelective surface flaking off. I have a suspicion that my old 96 CD holder is the culprit though.


I'd take a MiniDisc any day...

 

Well maybe you should take better care of your music.

 

not possible, the materials used to make those glasses would not function as a cd.

 

That type of material would not function as a CD.. a CD has to have divots/dents in it in order to store information.

 

CDs are made from polycarbonate plastic, also called "Lexan". The pits containing the digital information are contained in a thin aluminum layer coated onto the LABEL side of the disc, which is then overcoated with a thin plastic layer for protection, and the printed label.

Polycarbonate is seriously tough stuff. In fact, this is the material used to make the bulletproof windows at banks! With reasonable care, CDs hold up very well. If you do get a scratch on them, it can often be removed with a fine grade of plastic polish and a bit of elbow grease. Higher grade CD players (and many older ones) are more tolerant of scratches than the newer, cheaper ones.

The material used for scratch resistant eyewear is different, usually a methacrylate or other optical grade plastic. If CDs were made from this stuff, they would cost a helluva lot more than the obscene prices charged for them already. And the infrared laser used to play a CD might be absorbed by the plastic (or the surface coating) anyway.
