摘要： An optical device for illuminating an object with a rectangular pattern having a uniform light intensity distribution includes n (n.gtoreq.1) polarization separating elements which a laser beam emitted from a laser source enters and each of which separates the laser beam into two beams in two directions. The angle of separation by the polarization separating element is set to be 2.sup.(n-1) times of the smallest one of the separation angles of the polarization separating elements used. At least one quarter-wave or half-wave plate is combined with the polarization separating elements. An imaging lens is provided for forming 2.sup.n beam spots on the object such as an optical laser disk plate.

摘要： A magneto-optical data recording system comprises magnetic field pulse applying means for applying to a magneto-optic recording medium a magnetic field pulse of a polarity corresponding to code data to be recorded, and means for heating the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to be recorded. During recording, the magnetic field pulse applying means applies a magnetic field pulse of a polarity corresponding to code data along a track of the recording medium and the heating means continuously heats the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to thereby directly overwrite the code data. The magnetic field pulse applying means includes a magnetic coil driven by code data from a source of code data (data generator). The heating means includes an optical head which comprises a source of laser beam driven by a laser driver and an optical system which focuses the laser beam from the source of laser beam as a small light spot onto the recording medium.

摘要： An optical projection printing apparatus which can irradiate a mask with light from a first light source to focus the mask pattern on a resist of a semiconductor wafer in a highly accurate alignment by a first optical system including a projection lens. A wafer mark formed on the wafer to have a grating pattern shape is arranged to have its grating pitch direction located in the sagittal plane of the first optical system. The wafer mark is irradiated with the light coming from a second light source having a wavelength different from that of the first light source. Of the reflected light from the wafer mark, only the .+-. 1st order diffraction light is extracted by a filter and partially superposed on the mask in a transversely misaligned state so that the reflected light from the wafer mark may be focused by a second optical system. The aforementioned filter is disposed in the Fourier plane of the second optical system.

摘要： The present invention uses a magnetic recording medium equipped with those magnetically readable recording servo pits which are preformed on a magnetic recording medium and have different magnetic characteristics from those of a recording magnetic film, detects magnetically a tracking signal or preformat signals such as sync signals, address signals, and the like, from the magnetic flux distribution (leakage magnetic field) occurring at edges of each of the servo pits using a magnetic head, makes servo control of the position of the magnetic head by the detected tracking signal and records or reads magnetically the data along the center of a track. In the magnetic recording medium of the present invention, magnetically readable, wobbled servo pits or sync pits, track address pits and data pits are preformed on the magnetic recording medium, these pit portions have locally different magnetic characteristics from those of the recording magnetic film and have a magnetic film structure wherein saturated magnetization is smaller than at other portions or the magnetic film is removed locally. These preformed pits can be read magnetically by detecting the local magnetic field (leakage magnetic field) generated at their edges by the magnetic head.
