A while ago someone posted to this group that they were looking for very 
small motors and other parts for microbots. I was at a local surplus store 
yesterday and found a box full of drive assemblies for micro recorders. These
assemblies contain two interesting motors. One is the main drive it is 8mm
thick 3cm in diam and has a shaft that is 7mm long that is connected to a 
pully and speed sensor. This motor has a small rubber drive belt that goes 
around a large (3cm) brass wheel that drives the capstan. The other motor
is used to load and unload the head. At first I thought this was a small
solinoid but then I noticed it had a small worm drive on the end. It is about
1cm in diam and 8mm long it has a shaft of unknown length with a worm gear
on it. There are other misc gears and switches on the thing. They appear to
be brand new.  Each is in a small zip lock bag. They are marked $3.50 but
my instict tells me that if I buy enough that I may be able to get a deal on
them. If anyone is interested, my email address id miked@digibd.com
