<p>In a tracking control method and apparatus for an image recorder and/or reproducer, there are provided a method and device which can accomplish high-performance tracking control by using a variable capstan speed instruction which is reflected by a degree of tracking error instead of using a conventional capstan speed instruction wherein the tracking error is not reflected. For this, a tracking control method includes the steps of determining a 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 (S102), and determining the degree of speed error of the capstan motor (36) by comparing the capstan speed instruction with the actual rotation speed of capstan motor (36) (S106), and determining a degree of speed control of the capstan motor wherein the tracking error is reflected by performing a predetermined gain control on the speed error (S108). Thus, there are enabled rapid control wherein tracking compatibility during the control is improved, easy coefficient control and a single system. <IMAGE></p> |
