摘要： Tilt which is inclination of a normal of optical disk relative to optical axis of optical head is corrected with a liquid crystal element. In a driver for the liquid crystal element, a periodic waveform generator generates periodic waveform and an inverting element inverts the periodic waveform. The periodic waveform and the inverted waveform are connected to two ends of a potential divider which provides partial voltages. The periodic waveform is connected to a common electrode of the liquid crystal element, and the partial voltages of the potential divider are connected to electrodes opposing the common electrode. A structure of a driver circuit for each direction is simple. Tilt in a plurality of directions can be performed independently of each other. Spherical aberration is also corrected. When the liquid crystal element is mounted to a fixed component, deterioration due to jitters is reduced.

摘要： An objective lens driver includes a movable body, a base, a supporting portion, a first multipolar magnet and a second multipolar magnet. The movable body includes an objective lens, a lens holder, and a coil substrate. The coil substrate includes a focusing coil and a tracking coil. The supporting portion allows the movable body to move in a focusing direction and a tracking direction with respect to the base. The focusing direction is parallel to the optical axis of the objective lens, while the tracking direction is perpendicular to the focusing direction. The first and second multipolar magnets sandwich the coil substrate between them. The focusing and tracking coils are arranged as two flat coils on two mutually parallel separate planes so as to overlap with each other at least partially in a direction that is perpendicular to the focusing and tracking directions.
