Another obscure fact about 15" transcription disks.  Because they were
only intended for professional use, they often didn't have the "bead" on
the outside edge that commercial records have.  (The bead is the rounded
off edge.)  Without the bead, these disks had razor sharp edges.  I once
threw one of these things like a frisbie at a tree (with no one around,
of course), and it imbedded itself about 1" into the tree.  Makes Odjob's
hat seem like a safe children's toy.
