ABSTRACT:
A data-track accessing apparatus effectively eliminates external disturbance components from a track-deviation signal and correctly locates an objective track at an extremely fast speed. The apparatus includes an actuator which transfers a light beam in a direction of traversing tracks, a track-deviation detecting circuit which detects an amount of track deviation when the light beam traverses the tracks, a binary-coding circuit which converts the detected track-deviation signal into a binary-coded signal, an external-disturbance-component removal circuit which removes external disturbance components from the binary-coded track-deviation signal, and a speed-discriminating circuit which discriminates the moving speed of the light beam into multiple stages based on an output signal from the removal circuit.
