VELOCITY/PHASE STABILIZATION SYSTEM AND STABILIZATION CONTROL METHOD FOR SERVO SYSTEM

摘要

The stabilizing apparatus and control method stabilizes a running system by detecting a shortage area of a control pulse (CTL pulse) and by performing a regular speed control in the shortage area of CTL pulse by using a capstan pulse. The apparatus includes a speed controller, a recording phase controller, a play phase controller, a phase/speed controller, a play/recording switch and a phase/speed switch, a CTL shortage judging unit, a play/recording switching controller, and a phase/speed switching controller.
