摘要： An optical pickup device with the capability to read data from and write data to different kinds of optical discs in different formats and a composite optical device used in the optical pickup device. An optical pickup device is made by combining two laser couplers LC1 and LC2 that are designed for optimum read/write specifications for optical discs which are different in format from each other. In one embodiment, two laser couplers LC1 and LC2 are incorporated on a common photodiode IC to form a single laser coupler, and the laser coupler is used in an optical pickup device.

摘要： Apparatus for reading optically detectable indicia on a record carrier, such as video information which is recorded in the form of pits on a record medium, for example, a video disc. A source of coherent light transmits a beam to the record carrier. A hologram is interposed between the coherent light source and the carrier, the hologram serving to focus the beam on the record carrier. The intensity of the focussed beam is modulated by the recorded indicia, and at least one photodetector is disposed in an optical path traversed by the modulated beam so as to detect the intensity thereof. In a preferred embodiment, the hologram focusses the beam onto the surface of the record medium whereat it is modulated and reflected therefrom to the photodetector. Plural photodetectors may be provided in separate optical paths traversed by the reflected light so as to produce outputs which, upon comparison with each other, represent deviations, or tracking errors, in the location of incidence of the light beam on the record medium. In yet another embodiment, the hologram directs the coherent light to the record medium along two different optical paths so that the reflection of one beam can be used to read out the recorded information and the reflection of the other beam can be used to detect focussing fluctuations. In a still further embodiment, another hologram is used to receive and direct reflected light to the photodetector.
摘要翻译：用于在记录载体上读取光学可检测标记的装置，例如以记录介质（例如视频盘）上的凹坑形式记录的视频信息。相干光源将光束传输到记录载体。全息图被插入在相干光源和载体之间，全息图用于将光束聚焦在记录载体上。聚焦光束的强度由所记录的标记调制，并且至少一个光电探测器设置在由调制光束穿过的光路中，以便检测其强度。在优选实施例中，全息图将光束聚焦到记录介质的表面上，在该表面上被调制并从其反射到光电探测器。可以在由反射光穿过的分开的光路中提供多个光电检测器，以便产生在彼此比较时在光束在记录介质上的入射位置的偏差或跟踪误差的输出。在另一个实施例中，全息图将相干光沿着两个不同的光学路径引导到记录介质，使得可以使用一个光束的反射来读出记录的信息，并且可以使用另一个光束的反射来检测聚焦波动。在又一个实施例中，使用另一全息图来接收并将反射光引导到光电检测器。
