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.
摘要翻译：一种具有刀片的光学拾取器，所述刀片包括其中安装有物镜的第一刀片，并且由增强塑料材料制成;以及第二刀片，其中安装有驱动线圈并且由镁合金材料制成。由于第一叶片具有低导热系数，因此防止了线圈中产生的热量被传送到物镜，而具有高导热系数的第二叶片将线圈产生的热辐射到外部。因此，可以抑制物镜的热变形，并且可以避免对线圈的损伤或刀片的刚度降低。

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 device including a slider on which an objective lens is mounted and which is elastically movably supported by a support member, an air bearing member provided in the slider so that a lifting force pushes the slider away from the disk according to air flow generated during rotation of the disc, and an actuator to change the position of the objective lens mounted on the slider in a focus direction relative to the disc. In the optical pickup device, the slider is lifted from a disk using a lifting force acting on the air bearing member and simultaneously the position of an objective lens is adjusted by a piezoelectric device to perform focus control. Therefore, collision between a disk and an objective lens is avoided, and a focal position is effectively controlled just by changing only the position of the objective lens, thereby increasing the reliability of a recording and/or reproducing operation.

摘要： An actuator of a disc drive having a shock damping device includes an electro-magnet disposed on a cover of the disc drive, a magnetic material disposed on a load beam of the actuator, opposite to the electro-magnet, and a driving control portion controlling a driving of the electro-magnet by detecting an vibration of the load beam towards and away from an optical disc that is caused by an external shock. When the load beam is vibrated by the external vibration or shock to the disc drive, electricity is supplied to the electro-magnet, securing the load beam to the cover until the vibration ceases. Accordingly, even when there is external vibration or shock applied to the disc drive, possible damage to the disc or the actuator can be minimized or prevented.
