摘要： An optical disk unit has an optical system which is separated into a movable head assembly and a fixed optical system so that the movable head is made light weight. The movable head has an objective lens, an objective lens driving unit for focusing the objective lens, and a head moving unit for moving the whole movable head in the radial direction of an optical disk. The fixed optical system has a galvanomirror for deflecting the light emitted from a laser beam source and causing it to fall on the objective lens of the movable head, and detectors for receiving the light of the optical spot formed by the objective lens which is reflected from the optical disk. The galvanomirror is provided with a first mirror for reflecting the light emitted from the beam source to a plane intersecting the rotational shaft at right angles and directing the light to a fixed mirror, and a second mirror for deflecting the light reflected from the fixed mirror and directing the light to the objective lens. As a result, when the galvanomirror is rotated, the light reflected from the second mirror is constantly passed through a portion near the focal point of the objective lens of the light source side and falls on the objective lens.

摘要： A pickup and a drive, in a small size, having a spherical aberration correction device capable of correcting various spherical aberration, and coma aberration and/or astigmatism with a low power consumption. A variable-focus lens actuator can correct spherical aberration such that a transparent deformation film warps into a parabolic shape when a magnetic field is applied thereto, thereby changing the light intensity distribution of transmitted light. Further, the variable-focus lens actuator can correct coma aberration and/or astigmatism by arbitrarily tilting the transparent film to change the proceeding direction of the transmitted light.
