> Are X-Rays of any danger to CD-Rs or CD-RWs?

To complete the remaining 1.5 CEU's of this on-line course, there are at least
two URLs of interest. (This is homework people. There will be a test.)

For CD-R & CD-RWs:

For Magneto-optical drives:

Both of these techniques make use of highly localized heating to change the
crystalline structure of a very small region on a disc. While the physical
phenomenon employed is different, the basic answer to the question remains:
no. It would take extraordinary conditions beyond all hope of occurring for an
x-ray machine to locally focus enough energy on a disc to modify the
information in either a CD-RW or MO drive or disc.
