Are CDs considered 'magnectic storage devices'?
I recently had someone ship a couple of CDs to me for work purposes (containing Excel, Word, etc type files) that they had burned. When I got the CDs nothing was on them. Is it possible that CDs can be erased if they get close to magnetic devices? I looked at the FedEx site and this is what it had to say about shipping magnetic storage devices but I have no idea if a CD is in the classification. I couldn't find anything specifically about mailing CDs on the FedEx website (in there manual to be more accurate).
Magnetic Storage Devices
• Place 3 to 6 inches of protective material around the device to reduce the
intensity of magnetic fields that come into contact with it.
• Label the package “Keep away from magnetic material.”
• Items containing sensitive data should be encrypted and placed in a
securely closed package.

No, CDs are optical storage media. The data is read from them by measuring how light from a laser reflects from different sections of the disc surface. Data is written (on CDRs) using a different laser that burns the ink on the disc so it reflects light differently.
