Card reader head cleaning

I made a little "unprotect" card for my 65 so I can rewrite application pack cards that have degraded magnetically, and when inserting it from the left, I can feel a small increase in friction/resistance at about 1.5 inches in, and then it's blocked completely at 1.75 inches (I'm assuming it's hitting the drive wheel). Is that quarter inch of increased friction where the heads are located?

That's correct. The slight friction is the head, then you hit the drive wheel. The ball switches are further in which you won't get to from this side unless you force the card through the drive wheel.
