It's called diffraction - http://en.wikipedia.org/wiki/Diffraction.
The colorful rainbow on the back of a CD is caused by diffraction, where light waves are bent and spread out due to the closely spaced tracks on the CD. This diffraction creates the rainbow effect as different colors of light interfere constructively and destructively.
When you see a rainbow, you can enjoy its beauty and take a moment to appreciate the natural phenomenon.
No, a CD is not transparent. It is typically made of polycarbonate plastic with a metallic layer where the data is stored. The metallic layer reflects light, creating the rainbow effect commonly seen on the surface of a CD.
light is white. if you mix the colors of the rainbow you get white. A prism separates the colors, showing a rainbow.
No, the end of a rainbow is an optical illusion and cannot be physically reached or located.

The shiny side of the CD has a thin resin/plastic coating on it. This coating is thin enough to refract light, the same mechanism that creates a real rainbow.
You see a rainbow because you want to, and you do because you feel like it.
No, as you move the rainbow you see moves too. No, because the bit of the rainbow you see is part of a circle and circles have no end. However, you can direct someone else to the place where YOU see the end of your rainbow (but THEY will not see it when they get there).
There is no color your eye can see that is not in the rainbow.

No, different people may see slightly different rainbows depending on their viewing angle and distance from the rainbow. Each person's perspective will affect the portion of the rainbow they are able to see.
No. In order to see a rainbow in front of you, there must be a source of light behind you, and the rainbow you see will only have the colors of the source in it.
One doesn't have to be at any specific angle to see a rainbow. What is Dependent on seeing the rainbow is the location of the rain, and sun relative to you. The sun is always behind a rainbow when seen. So you would be in front of the rainbow, rain, and the sun. Also, No two people see the same rainbow unless a picture or video was taken of the rainbow.
