ABSTRACT:
A magnetic recording and reproducing apparatus includes a control device for monitoring a take-up reel, a feed reel, and a capstan motor for rotational speed and direction. By monitoring the take-up reel, feed reel and capstan motor, the control device determines if the apparatus is operating properly. Based on the determinations regarding the proper operation of the apparatus, the control device controls the operation of the capstan motor and the shifting of the idler gear between a first operational state and a second idle state.
