I have read on several occasions about the mylar on both faces of the
tape.  I have over 300 reels of DECTape in my collection.  Most of these
are 3M Scotch branded but around 30 of them are DEC branded in the blue
plastic boxes.  I have never seen one with mylar on both sides.  This may
have been something that existed early on but certainly wasn't the norm.
