 I just move the head assembly a bit, there is an interlock mechanism that
 stops the heads going across the disks, but there is a bit of play in it
 usually which should allow you to unstick them. However, that usually is not
 enough to cure the problem because the bumpers have turned to sticky goo and
 the next time the heads touch the goo they will stick again. 
Just to be sure: there is one "bumper"? Or more than one?
(Yeah, this will be obvious once I open the thing, but it is good to
be prepared)
  I just use a Post-It, really anything will do, you
just need to cut a narrow
 enough strip to go into the gap where the bumper is. One thing to be aware
 of is that the disk can be sensitive to the thickness of the paper. If you
 completely remove the goo you need to experiment with multiple layers of
 paper until the starting position of the heads is just right, otherwise you
 will end up with the same stop-start behaviour. 
I was thinking that I could just stick the paper to the goo on the bumper.
If not,  I will need to find a way to attach the paper to the bumper.
