I don't think X-rays should affect a magnetic disc--I don't know how
the metal detectors work, though, and don't know if there are any
magnetic detectors of any kind nowadays (though you'd think that would
endanger computer hard drives and credit cards, which they apparently
don't do). I've passed through several airports with minidiscs that
were not erased (but got too close to our MRI scanner once, and it
erased all the magnetic strips on all my credit cards, and completely
wiped the memory from my Palm Pilot).
