Abstract: A laser tracking system is provided to track motion of an object with a laser beam by irradiating the laser beam to form a circular beam pattern on the object and using the circular beam pattern. A laser source(110) irradiates a laser beam to an object. A rotating disc(130) has a reflection surface(130a) for reflecting the laser beam and is rotated around a first axis tilted to a perpendicular line of the reflection surface. A beam adjustor(170) changes a path of the laser beam reflected from the rotating disc to the object. An optical detector(190) detects an optical signal reflected from the object. A motion calculator(210) calculates motion of the object from the detected optical signal. A controller(230) enables the laser beam to track the object by controlling the beam adjustor according to information calculated in the motion calculator. The beam adjustor includes a mirror(173) and a biaxial actuator(176) rotating the mirror to two rotating axes perpendicular to each other. A time trace of the laser beam reflected from the reflection surface forms a circular shape as the height from the surface perpendicular to the first axis to one end of the reflection surface forms a sine wave to time.

Abstract: A system for tracking laser with improved sensitivity is provided to improve the sensitivity by easily detecting a laser signal reflected from an object in distinction from an external optical signal. A laser source(310) irradiates a laser beam to an object(O). An optical detector(410) detects an optical signal reflected from the object. A first blocking member(360) has a cylindrical shape, is arranged close to the optical detector, and prevents the optical detector from receiving the light excluding the optical light reflected from the object. An operation calculator(430) calculates movement of the object from the detected optical signal. A control mirror(330) is controlled to follow the laser beam to the object based on the information calculated in the operation calculator. A beam splitter(350) enables the light to face the control mirror by penetrating the light received from the laser source on an optical path between the laser source and the control mirror, and enables the light to face the optical selector by reflecting the light reflected from the object and the control mirror.

Abstract: A disc cartridge includes a shutter unit having an outer shutter and inner shutters to open and shut apertures on the disc cartridge. The outer shutter opens one of the inner shutters corresponding to a side of the disc cartridge being accessed by a pickup. Accordingly, the overall area of the apertures exposed to the exterior during information recording and reproducing operations is reduced. Accordingly, dust is less likely to enter into the disc cartridge.
