    • A method and apparatus for compensating tilt. The tilt compensation method includes: obtaining one of a jitter best, an RF envelope, and a focus DC offset (FODC) from a detection signal of the ROM data region and determining whether the obtained value is within a tolerance range; and obtaining an initial skew compensation value using the obtained value when the obtained value is within the tolerance, changing the magnitude of current applied to an actuator designed to perform driving in at least three-axis directions to drive an objective lens of an optical pickup assembly in a radial tilt direction when the obtained value is not within the tolerance range, and repeating the obtaining of one of the jitter best, the RF envelope, and the FODC and changing the magnitude of the current until the obtained value is within the tolerance range.

    • A lens position determination apparatus of an optical pickup includes a lens holder with a mounted lens, a base supporting the lens holder, and a pressing member. The base has an accommodation surface accommodating the lens holder and a pair of facing support walls on the accommodation surface. The pressing member is a bendable arm. A first elastic portion between arm end portions applies an elastic force in a direction in which the arm end portions closely contact the support walls. A second elastic portion connected to the arm presses the lens holder toward the accommodation surface to fix the lens holder position. The lens adjustment can be performed while the pressing force to fix the lens holder to the base is removed by bending the pressing member into a V shape to reduce frictional resistance of the lens holder with the base during the adjustment.
    • 光学拾取器的透镜位置确定装置包括具有安装的透镜的透镜保持器,支撑透镜保持器的基座和按压部件。 底座具有容纳透镜架的容纳表面和在容纳表面上的一对相对的支撑壁。 按压构件是可弯曲臂。 臂端部之间的第一弹性部分在臂端部紧密接触支撑壁的方向上施加弹性力。 连接到臂的第二弹性部分将透镜保持器朝向容纳表面压住以固定透镜保持器位置。 可以通过将按压构件弯曲成V形来消除将透镜保持器固定到基座的按压力,从而在调整期间减少透镜架与基座的摩擦阻力。
