I am trying to create a realistic looking CD, but have no idea how to give it the chrome edges and so on. Does anyone have a clue as to how to do this?

If you mean making those 'rainbow'-like colors, than there's no other solution than just making your own (2D) texture. Or at least I don't know any other solution.

I'm speaking of CHROME, as in metal, not some oil slick looking material. I realize CD's give off that rainbow effect, but I would like to be able to have a chrome looking one. I can't seem to find a chrome material anywhere.

Wouldn't some tweaking to brushed silver or even polished silver work?

To create chrome the metal needs to be highly reflective and it usually needs to have a high metalicity setting to look convincing. A nice brushed-silverlike specularity might also help, but that depends on the lighting of the scene.

Fast Trax has a chrome material for doing faux-Sorayama robots, but it uses a fake reflection, and only works in the right sort of scene. I would have thought you could get the effect you want by judicious tweaking of high reflectivity, high specularity, low diffusion and low ambience.

There's a chrome metal texture in your simple & fast directory along with a mirror texture. Why they weren't in metals and glass directories I don't know. They are procedural so you can tweak the daylights out of them. If that doesn't work, check out the link.
