I have an old Pioneer PD-8700 which sticks on certain CDs.
Obviously the sensible thing to do is to throw it away
and get another from the local charity shop.
But it would be amusing to get out the scope and try to align it.
It needs a (Sony?) YEDS-7 test CD, which would be very expensive
if it were available.

Does anyone have any idea what's on the test CD?
Is there another which would work instead?
Or is it the sort of thing which can be copied so that at
least the Pioneer could be aligned similarly to the cd writer
on my laptop. If so, does anyone know of any images available?
