Inventor: MIZUNO SADAO
IPC: G11B7/135
Filed: 1986-07-11
Abstract: PURPOSE:To eliminate a relative positional shift between two light spots in the direction orthogonal to a track and to secure the stable irradiation with a double laser beam head, by enlarging an oval light beam radiated from a semiconductor laser in the track direction and shaping the enlarged beam into an approximately circular from. CONSTITUTION:A light beam 2 radiated from a semiconductor laser 1 is turned into parallel beams through a condenser lens 3 and refracted as soon as it passes through an enlargement face 5 of a prism 4 by P polarization. Then the diameter of the refracted beam is increased in the track direction and shaped into an approximately circular form. Therefore the optical axis is totally reflected by a reflecting face 8 of a prism 7 and reaches a wavelength selection filter 9, an optical path changing triangular prism 10, a 1/4 wavelength plate 11 and an aperture lens 12. Thus a light spot 14 has a shift in the track direction on a disk 13 even though the optical axis of the beam 2 has a shift. So is with a light beam 27 which is radiated from a semiconductor laser 26 and shaped into an approximately circular form. Then no tracking error is produced.

Abstract: PURPOSE:To increase a signal light quantity on the observation surface, and to improve the S/N ratio by placing an optical system having a negative refracting power in the vicinity of an optical modulating element, and increasing a separation angle between a modulating luminous flux and a non-modulating luminous flux. CONSTITUTION:A luminous flux which is made incident on an optical modulating element 31 from an illuminating optical system 32 through a cylindrical lens 34 is reflected by a fixed light reflecting surface 20 of the optical modulating element 31, and a minute reflecting surface 22 which gives no modulating operation, and thereafter, passes through the cylindrical lens 34 again, and thereafter, an image 35 of a light source 32a is formed. In an image forming optical system 36 for photodetecting the luminous flux which is modulated and deflected by the minute reflecting surface through the negative cylindrical lens 34, its optical axis 37 is placed so as to be orthogonal to the array direction of the minute reflecting surface. The non-modulating luminous flux forms an optical image 35 on the optical axis of the illuminating optical system 32, and on the other hand, the modulating luminous flux receives a divergence action of a concave lens 34, therefore, a separation angle to the non-modulating luminous flux is amplified.

Abstract: PURPOSE:To eliminate the defect of leakage by providing the positions of forming both of anode and cathode electrodes outside above the P-N junction. CONSTITUTION:A region 3 serving as the cathode region is formed not in the anode region 4, but across the region 4 and a substrate 8. The cathode electrode 1 and the anode electrode 2 can be formed outside above the P-N junction 7, and, even when the depth of the junction 7 is the same as conventional, the cathode electrode 1 is placed outside above the junction 7 by means of a diffused region 3'; thereby an alloy layer 5 does not reach the junction 7. Besides, even if the alloy layer 5 advances to the depth direction, leakage never occurs, since the part immediately under the layer 5 is of the same conductivity type as that of the region 3'.
