    • An magneto-optical disk drive comprises a driving apparatus for rotating a medium, an electromagnet positioned above or below the medium for producing a magnetic field on a recording surface of the medium, and an optical head by which laser light illuminates the recording surface and the laser light reflected from the recording surface is picked up. Here, the electromagnet comprises a plurality of subdivided electromagnet elements, a magnetic field concentrator by combining the electromagnet elements in a magnetic circuit and concentrating magnetic fields produced from the combined electromagnet elements on a portion of the electromagnet, and a center magnetic pole provided in an opposing position with respect to the optical head, to thereby make the magnetic field concentrated by the magnetic field concentrator pass through the recording surface of the medium. Accordingly, the recording time or data on the medium becomes greatly shortened, thereby enabling high speed data recording.

    • An optical pickup for recording and reproducing information via a magneto-optical disk comprises a phase-diffraction grating which is diffracted in two directions perpendicular to each other on a plane perpendicular to a beam axis. The diffracted light of the phase-diffraction grating has a different phase for each direction, and the phases are varied according to the polarization angle which is rotated by the Kerr effect of the magneto-optical disk. The reproduction signal is detected using the intensity variation of the diffracted light of the two directions due to the phase change. Also, the focus error signal according to the oscillation of the magneto-optical disk is detected by condensing the diffracted light of the phase-diffraction grating by means of the condensing lens and using the amplitude change of the diffracted light. Such an optical pickup is not affected by the variation of the light quantity, thereby contributing to clear reproduction and the enhancement of the signal-to-noise ratio.
    • 用于通过磁光盘记录和再现信息的光学拾取器包括在垂直于光束轴线的平面上彼此垂直的两个方向衍射的相位衍射光栅。 相位衍射光栅的衍射光对于各个方向具有不同的相位,并且根据由磁光盘的克尔效应旋转的偏振角而改变相位。 使用由于相变引起的两个方向的衍射光的强度变化来检测再现信号。 此外,根据磁光盘的振荡的聚焦误差信号通过聚光透镜使衍射光栅的衍射光聚光并利用衍射光的振幅变化来检测。 这样的光学拾取器不受光量的变化的影响,从而有助于清除再现和提高信噪比。
