This actually sounds as though it could be the grain of the paper on 
which the magazine was printed. It's an extremely regular, constant 
sound and one that could easily be imagined as coming from a paper disc 
being "played" by an acoustic pickup.

I used to do this with labels of junky records on my Victrola XVI when I 
was a teenager, cutting spirals into the labels, which is how I 
recognized the pattern.

I don't know if Dr. Feaster is on or reads ARSCLIST. I know he used to 
be a fairly heavy participant in 78-L years ago.
