It seems that CD-R or DVD-R contain a thin film of aluminium.
I wonder if metal detector is capable to detect a pack of CD-R, and at what distance (depth) ?
Could anybody do some tests and compare the detection distance (if any) to this of a coin ? How position of CD-R (flat/edge) affects detection ?
