I am going to be traveling home this Christmas for 2 weeks and taking a lot of pictures. I plan to save my photos to CDs and then bring the discs back with me in my carry-on camera bag. Are CD-Rs (I use memorex brand) effected by the airport security machines/x-ray machines. I know that memory cards are not.
I have carried CD-Rs with me on many trips, and have yet to have one damaged by airport X-Rays. Especially the ones that check carry-on bags.
For safety's sake, though, I recommend making 2 copies of the CDs before erasing the memory cards.
CDs will not be affected by airport x-rays. Neither will your memory cards. X-rays, as a form of light near the visible spectrum, will affect film but not CDs (that are "burned" and permanently changed by recording).
I reccomend making copies of the CDs to put in differnet luggage as the biggest risk is loss of a bag. Cameras can be replaced but photos cannot.
