Abstract: A sled motor controlling method for shifting the position of an optical pickup a CD-ROM drive is disclosed. According to the inventive method, the number of tracks from an initial position of a pickup to a target position are counted. A timer interrupt, of a timer inside the CD-ROM, is enabled for acceleration to and rotation at constant speed of a sled motor which moves the pickup. The ennoblement of the timer interrupt is based on a number of reference clock pulses which correspond to the number of tracks to be traversed. A determination is made whether the pickup is approaching the target position. If it is determined that the pickup is approaching the target position, a timer interrupt is enabled for deceleration of the sled motor. Then, all timer interrupts are disabled if it is determined that the pickup has reached the target position.
