I actually have some Laserdiscs (a whole other story), and I used one that didn't have material recorded on one side. If you must know it is the 90's classic Stargate. When I placed the stylus down, it seems to stay pretty still, not totally, but enough to keep it from moving inward. I hear that it is hard to do a test this way, since there are no grooves, but wanted to try it. I hope this shows my anti-skate is working properly.
