These Japanese Miny brand tape recorders feature three inch reels. 

     They are rim drive recorders. This was the cheapest drive that could be manufactured.   More expensive recorders used and still use a capstan system that runs the tape at a constant speed across the head.

      With rim drives the motor shaft presses directly against the rim of the reel platter.  When there is a lot of tape on the pulling reel, the tape runs much faster across the head than if there is just a little.

      Because of the varying tape speed, it is impractical to play these tapes on the higher quality capstan drive machines.  You will get chipmunk talk at the beginning and very low slow mush talk toward the end.
