8 Reverse Rotation Preventing Function
Reverse rotation prevention circuit has a function for intercepting the reverse rotation of MD.
When SERVO control input is EC<ECR, MD rotates forward and Q which is the output of D-F/F goes "High".
When SERVO control input is EC>ECR, motor puts on reverse brake and MD speed is rapidly reduced.
When SERVO control input remains EC>ECR, MD rotates reverse and Q which is the output of D-F/F goes "Low", in
result current sense amp is interrupted. Accordingly gain controller goes OFF and motor is stopped.
