SF354 SSDD Drive Belt

Ive got a drive that I hear the motor spin, but not the disk. Upon disassembly I see a large wheel on the bottom with wht looks like part of an old belt stuck on it, about 3/4 of the circumfirence. I dont see anywhere else a belt could attach to. It is a chinon mech with a rhombus shaped eject.

A) did this drive have a belt?
B) where could i possibly source one?

Thanks on advance
