摘要： An optical head includes a substrate, a laser diode, a photodetector, an objective lens, a prism, and an optical element. The laser diode is installed on the substrate and emits light. The photodetector is installed on the substrate and receives the light. The objective lens is installed on a first side of the substrate and focuses the light emitted from the laser diode onto a recording surface of a disc. The prism is installed on a second side of the substrate, transmits the light emitted from the laser diode toward the objective lens, and transmits the light reflected from the recording surface toward the photodetector. The optical element adjusts an optical path formed between the substrate and the prism.

摘要： An objective lens driving apparatus for an optical pickup includes a blade on which an objective lens can be mounted, a plurality of elastic support members supporting the blade and capable of elastically moving with respect to the blade, and a servo mechanism driving the blade up and down, left and right, and in a rotational direction. The elastic support members are grouped into pairs arranged to face each other with respect to a center of rotation of the blade, and distances between the elastic support members in the respective pairs are substantially identical. By lessening the difference in the amount of deformation between the elastic support members supporting the blade during tilt control, the elastic support members are less likely to move in undesired directions when vibration is applied.

摘要： An actuator used with an optical pickup to drive a blade, on which an objective lens is mounted, in focusing and tracking directions, includes a pair of magnets installed on a base, and a plate coil installed in the blade to be placed between the magnets. Each magnet has a shape in which N and S poles of the magnet are alternately magnetized in four regions asymmetrically split vertically and horizontally. In this structure, the actuator used with an optical pickup can be less affected by sensitivity variations when the blade is displaced, and the size of the electromagnetic driving unit can be reduced by reducing the number of magnetized gaps formed in the magnet.

摘要： An optical pickup having a blade including a first blade in which an objective lens is mounted and which is made of a reinforced plastics material, and a second blade in which driving coils are mounted and which is made of a magnesium alloy material. Since the first blade has a low thermal conductivity coefficient, the heat generated in the coils is prevented from being transferred to the objective lens, whereas the second blade having a high thermal conductivity coefficient radiates the heat generated by the coils to the outside. Thus, the heat distortion of the objective lens can be suppressed, and damages to the coils or rigidity reduction of the blade can be avoided.

摘要： A mobile terminal executes a navigation function by receiving Transport Protocol Experts Group (TPEG) traffic information through a Digital Multimedia Broadcasting (DMB) network. This DMB-based mobile terminal receives and decodes TPEG data at a separate second processor different from a conventional first processor. Further, the DMB-based mobile terminal may execute a calculation of an optimum route at the second processor. The terminal and a related method reduce the processing load of the first processor, which causes a decrease in the response time to a user's navigation request and improves a user's convenience.
