My daughter is doing a science fair project on how extreme temp's affect CD?

Question

She is to find reference data to support the fact that extreme temp's will damage the CD but is having trouble finding anything. Can you may any suggestions?

Answer 1

try wikipedia

Answer 2

Try various resources. You can carry out an experimet as well. As far as I know, CDs are made out of plastic... extreme tempratures cause the plastic to bend resulting in damage to data.

Try looking for information from manufactures of CD's and or CD players. If you have time, have her contact the companies via e-mail or by phone to get data. make sure you cite your souce. This website from a CD player manufacturer says that high temperature may warp the disc. http://www.weltonusa.com/pdfs/omcdc86.pdf

Do your own research. Freeze one then see how it plays.
