Most of the recorder movements currently on the market do not have a fully automatic stop device. With this type of movement device, the tape recorder is prone to belt failure, and even damages the motor of the movement. I recently installed a fully automatic shutdown circuit in the recorder. This type of failure is basically eliminated.
