No they are not. Biodegrable means that they will break down simply via the effects of the environment; sun, rain, etc., But since CDs are plastic I would think they are recyclable i.e. they can be mechanically broken down and remade into some other product...perhaps a water bottle.
No. Compact Discs are made from an aluminum reflective layer between two clear layers of plastic.
how long does a crisp packet to biodegrade
How long it takes for an aluminum can to biodegrade
It takes 1000 years for it too biodegrade and that is if it is buried. :)

a long time.
5 to 10 years.
Eraser is made out of rubber. If exposed under the sun, an eraser will take between 50 to 80 years to biodegrade.
A disc's lifetime is measured by the number of years for which the medium can store the data successfully in it. A typical cd exists for around 217 years - so that would be its lifetime.
