There was a tape sold by a few manufacturers (I think 3M's 
was called Black Watch) that had a coarse black matte finish 
on the back side.  A problem with some drives which had fast 
rewind speeds was that air was trapped in the tape wind, and 
then once a bunch more layers of tape was wound on the reel, 
the tape wrap would cinch and fold over a piece of tape.  
This matte finish was supposed to cure that, and I think it 
did.  But, that finish was not as durable as the magnetic 
coating, and would start to shed all over the drive, leaving 
stuff on the data surface.  I think about 5 years after the 
stuff came out, most data centers searched out and trashed 
all these tapes.
