摘要： An optical pick-up generates a 0-th order diffraction light and ±1st order diffraction lights by a diffraction grating and irradiates the same to an optical disc. The ±1st order diffraction lights have phase distributions equivalent to a wavefront aberration of the optical disc when there is a tilt in the optical disc. Distances between the center of the main optical spot and centers of sub optical spots in a disc radial direction on a recording surface are whole multiples of a track pitch. The generation circuit generates a main push-pull signal corresponding to the 0-th order diffraction light and first and second sub push-pull signals corresponding to the ±1st order diffraction lights and generates tracking error signals TE as differential push-pull signals obtained by subtracting a sum signal of the first and second sub push-pull signals from the main push-pull signal.

摘要： In a semiconductor memory device according to the present invention, a conductive layer is formed on a field oxide film in a boundary region on the main surface of a semiconductor substrate. A floating gate electrode, an interlayer insulating film, and a control gate electrode are formed on the semiconductor substrate in a memory cell array region with a gate insulating film interposed therebetween. A gate electrode is formed in a peripheral circuit region with the gate insulating film interposed therebetween. An interlayer insulating film is formed on the conductive layer, the gate electrode, and the control gate electrode. A contact hole is formed at a predetermined position of the interlayer insulating film. An interconnection layer is selectively formed on the interlayer insulating film including the inner surface of the contact hole. According to the present invention, it is possible to prevent formation of a concave portion on the surface of the field oxide film in the boundary region. It is also possible to protect the memory cell array region from an external noise by forming the conductive layer on the field oxide film in the boundary region and by fixing the potential of the conductive layer.

摘要： Disclosed is a method for recording and reproducing sector control information to and from a novel magneto-optical disk to which the so-called erasure type data reproduction method or data-embossed type reproduction method applies. On the magneto-optical disk, sector control information is recorded onto a sector control information recording region at a track recording density lower than that of a data recording region. When data is recorded on the disk at a high track density, the sector control information is recorded in such a manner that the information will not exist on adjacent tracks along the same radials of the disk.
