Tracking control method and apparatus for controlling capstan motor speed
 In tracking control method and apparatus thereof for an image recorder/reproducer, there are provided a method and device which can accomplish a high-performance tracking control by using the variable capstan speed instruction which is reflected by the degree of tracking error instead of using the conventional capstan speed instruction wherein the tracking error is not reflected. For this, a tracking control method includes the steps of obtaining the degree of tracking control by performing a predetermined gain control on the tracking error, and generating the variable capstan speed instruction wherein the degree of tracking control is reflected, and determining the degree of speed error of capstan motor by comparing the capstan speed instruction with the actual rotation speed of capstan motor, and obtaining the degree of speed control of capstan motor wherein the tracking error is reflected by performing a predetermined gain control on the speed error. Thus, rapid control wherein tracking compatibility during the control is improved, easy coefficient control and single system, are enabled.
