摘要： An improved output unit used in recording information on a recording medium is disclosed which comprises a plurality of output parts and in which recording of information is carried out while changing the relative position between the output from the output parts and the recording medium. The improved output unit according to the invention is characterized in that the output parts are arranged in rows in a predetermined direction and are disposed in such a manner that information may be put out selectively from the output parts so as to prevent information from being recorded in overlapping fashion on the recording medium in a manner as often occurs in the conventional unit. Spacing between the output parts is selected large enough that the output parts are easy to manufacture. Since a plurality of output parts can be operated very effectively, extremely high recording efficiency is achieved using the information output unit according to the invention. Also, it is possible to use a recording medium having a relatively low sensitivity and which is generally cheap in cost, for carrying out a high speed recording.
摘要翻译：公开了一种在记录介质上记录信息中使用的改进的输出单元，其包括多个输出部分，并且在改变输出部分的输出和记录介质之间的相对位置的同时执行信息的记录。根据本发明的改进的输出单元的特征在于，输出部件沿预定方向排列成行，并且以可以从输出部分选择性地放出信息的方式设置，以防止信息被记录在在常规单元中经常出现的方式在记录介质上重叠。输出部分之间的间距选择得足够大，使得输出部件易于制造。由于可以非常有效地操作多个输出部分，所以使用根据本发明的信息输出单元实现极高的记录效率。此外，可以使用具有相对低的灵敏度并且通常成本低廉的记录介质，用于执行高速记录。

Optical separating structure is provided for dividing a light beam reflected by the recording medium, with modulation of its polarization state in accordance with the recorded information, into first and second light beams which are polarized in directions perpendicular to each other. First and second light detectors respectively detect the first and second light beams. Preferably, a single lens is located between the separation structure and the first and second light detectors for converging the first and second light beams. Also preferably, the first and second light detectors are formed on the same substrate and are each divided into a plurality of light receiving areas. Further, an amplifier circuit is preferably formed on the same substrate as the first and second light detectors. Where the amplifier is a differential amplifier, it may produce an information signal by differentiating output signals of the first and second light detectors.

摘要： An optical pickup device for producing information magnetically recorded on a recording medium includes a light source for generating a light beam polarized in a predetermined direction. An object lens is provided for focusing the light beam generated from the light source onto the recording medium. A beam splitter is arranged in an optical path extending from the light source to the recording medium, the beam splitter having a reflection plane for reflecting the light beam from the light source toward the recording medium. The beam splitter simultaneously causes the reflecting light from the recording medium to pass through the reflection plane to separate the reflected light beam from the light beam irradiated toward the recording medium. The polarization state of the reflecting light beam is modulated in accordance with the recorded information. The beam splitter splits the reflected light beam passed through the reflection plane into first and second light beams both of which are polarized in directions perpendicular to each other. The beam splitter has a bi-refractive property. First and second detection circuits are also provided for detecting the first and second light beams, respectively, and for providing first and second detection outputs respectively corresponding thereto. Circuitry is also provided for differentiating the detection outputs from the first and second detection circuits to provide information signals.
