    Abstract: A tracking control method and apparatus of an image recorder/reproducer enable high performance tracking control by generating a capstan motor speed control value using a variable capstan speed command onto which a tracking error control is reflected. The method includes the steps of obtaining a tracking control value by performing a predetermined gain control on a tracking error; generating a variable capstan speed command onto which the tracking control value is reflected; determining the speed error of a capstan motor by comparing the capstan speed command and the actual rotating speed of a capstan motor; and obtaining a speed control value of a capstan motor onto which a tracking error is reflected, by performing a predetermined gain control on the speed error.
