I remember a thread about transparant aluminium that later turned out to be some other alloy (or metal) and the double sided CD's and the multiple layer CD's that made up 40GB or something.. but I cant remember transparant CDs sorry..

There used to be transparant vinyl :D I had a one with a funny shape too..

Oh dear, oh dear...

Now you're showing your age Neobond :cheeky: , My mum's got transparent vinyl!

As for the CD, I remember the thread, I just can't find it.

Doing a search for "transparent" simply throws it back in my face.

It was a hoax - the guy posted a picture of the plastic, clear CD-protector that comes on most CD-spindles. Transparent CD's are SO FAR impossible to create.

Yep, sounds about right. I remember the story as being a fake.

And yeah, the laser needs something to reflect off of, Space Guy was on the ball yet again ;) .

I have been to a cd manufacturing warehouse and cd's when they write the data on them are transparent. they add the silver finish afterwards...so in a way you are both right. They also paint the top of them afterwars too.

When I was there in Santa Clara, they were making SoundBlaster Driver cd's which needed 4 colors, orange, blue, white and I dont remember the other color. Also they were making IronCAD cd's. Its pretty cool stuff. WISH I worked there.....heh heh...just taking home some rejects...LOL

I was under the impression that the silver layer had fine imprints so the laser could read it (like vinyl) I'm sure its done that way

Correct:

A CD is a fairly simple piece of plastic, about four one-hundredths (4/100) of an inch (1.2 mm) thick. Most of a CD consists of an injection-molded piece of clear polycarbonate plastic. During manufacturing, this plastic is impressed with microscopic bumps arranged as a single, continuous, extremely long spiral track of data. We'll return to the bumps in a moment. Once the clear piece of polycarbonate is formed, a thin, reflective aluminum layer is sputtered onto the disc, covering the bumps. Then a thin acrylic layer is sprayed over the aluminum to protect it. The label is then printed onto the acrylic. A cross section of a complete CD (not to scale) looks like this:

If it was real SO WHAT?? so when you take the CD out of the case you can look through it the whole 5 seconds between "out of case and into CD tray" LOL

Transparent CDs will only enhance fingerprints ;)

'and that was funny because?'

It was ever so slightly futile (are you going to say that to every '*'d thread?), and leads me further towards the conclusion that neowin is turning into a playground for bored schoolkids.

I doubt you could get a transparent cd, unless you can get the metal film so thin that it appears completely transparent, but is still thick enough for the pits, and has the qualities needed to reflect enough light.

Having said that, some cds are partially transparent at certain angles, I'd guess it maybe possible to get largely transparent cd's.

//edit : Think about the mirror coating you can get from your local opticians (at a cost). It allows you to see through the lenses, but only reflects light from the other side (unless you get very close).

Similar to police interview room windows I guess. I'm sure that technology could be developed and applied.

I'm still sceptical, expecially as this was dated fall '00 and it's approaching 2 years later.

And like Neobond said, the point of it is???
