摘要： Astigmatism of a beam of first laser light is cancelled at a position separated from first optical element by a predetermined distance on an optical axis of the beam of first laser light by refracting to transmit the beam of the first laser light by being refracted by rotating by a predetermined angle around an axis orthogonal to the optical axis of the beam of the first laser light, refracting a beam of second laser light to coincide with the optical axis of the beam of the first laser light and rotating by a predetermined angle around a second axis orthogonal thereto.

摘要： An optical disk device has an aperture of an objective lens in an incoming path of a beam from a semiconductor laser to an optical disk formed larger than an aperture in a return path from the optical disk or an aperture is varied in recording and in reproduction. This configuration improves recording/reproducing ability since light is focused on an optical disk with high numerical aperture. In addition, since reflected light from the optical disk is detected with low numerical aperture, margins for tilt and defocus are not reduced. Furthermore, since unnecessary signal components contained in the reflected light can be eliminated, a S/N (signal-to-noise ratio) of an information signal also increases. Thus, a high-performance optical disk device can be obtained. Alternatively, by varying the aperture of an objective lens in recording and in reproduction, an optical disk device in which recording density and recording quality are increased without deteriorating reproduction quality can be obtained.

摘要翻译： 光盘装置在从半导体激光器到形成大于来自光盘的返回路径的孔径的光盘的入射路径中具有物镜的孔径，或者在记录和重放中变化。 这种配置改善了记录/再现能力，因为光聚焦在具有高数值孔径的光盘上。 此外，由于以较低的数值孔径检测出来自光盘的反射光，因此不会降低用于倾斜和散焦的余量。 此外，由于可以消除包含在反射光中的不必要的信号分量，信息信号的S / N（信噪比）也增加。 因此，可以获得高性能光盘装置。 或者，通过在记录和再现中改变物镜的孔径，可以获得其中增加记录密度和记录质量而不恶化再现质量的光盘装置。

摘要： A laser driver circuit comprising a current supply circuit for supplying a laser diode with a current is provided. The current supply circuit comprises a voltage-to-current converter circuit, a current output line for outputting the current generated by the voltage-to-current converter circuit, a current supply line connected to the laser diode, a ground line connected to the ground, and a current path switch for selectively connecting either the current supply line or the ground line to the current output line. The laser driver circuit further comprises a current output prevention circuit for preventing the voltage-to-current converter circuit from generating the current by disconnecting the voltage input line using a voltage input switch so that the voltage is not input to the voltage-to-current converter circuit, when the current output line and the ground line are connected by the current path switch.
