I have a Brother Correctronic (mine from college).  It has a lift off correction tape, and it works very well.  I'm not sure if that is what you are talking about? 

I had ordered some of the black/white ribbon, where the white is correction film.  It does not play well in most of my machines.  Something about the correction part makes it not want to feed through vibrators very well.  I have it installed in a Remington Letter-riter right now, and it is working fine.  For this, you backspace to the mistake, switch the color selector to red and correct the mistake, then switch back to black.  It works similarly to correction film. I've heard that the white can eventually start to flake when it gets old, and make the inside of the machine messy, but if that happens I will just clean and put in a different ribbon.
