Title: Light source for optical head
Inventor: FUJIWARA MASAHIKO
IPC: G11B7/12
Filed: 1982-05-12
Abstract: PURPOSE:To obtain a beam which contains two wavelengths and is coincident with optical axes, by fusing the 1st and 2nd lasers onto a heat sink with their end faces set adjacently to each other so that the radiated light of the 2nd laser is connected to a 3-dimensional optical waveguide of the 1st laser having a wavelength different from the 2nd laser. CONSTITUTION:A semiconductor laser LD20a of an oscillating wavelength lambda1 is provided together with a semiconductor laser LD20b of a wavelength lambda2 longer than the lambda1. These two lasers are fused onto a heat sink 22 with their end faces set close and opposite to each other so that the output light of the LD20b is connected to a 3-dimensional optical waveguide formed at the light emitting part of the LD20a. In such constitution, the output of the LD20b is propagated at the inside of the LD20a and radiated from the end face of the LD20a in the form of output light 21c together with the output 21a of the LD20a. As a result, it is possible to obtain a light beam which contains two different wavelengths having optical axes coincident perfectly with each other. This process produces a light source for optical head which has easy control of its optical system and high reliability.

Abstract: PURPOSE: To reduce the extension of vertical retracing due to a feedback signal. CONSTITUTION: A vertical deflecting amplifier 53 has an output transistor(TR) Q1 which operates as a conductive switch for coupling a boosted source voltage with a vertical deflecting winding LV in a vertical retracing period.

Filed: 1989-03-30
Abstract: PURPOSE:To perform polarizing multiple recording excellent in recording stability by uniformly orienting an association compound of a dye in the horizontal direction of a recording layer to provide anisotropy to said recording layer. CONSTITUTION:For example, a photochromic material having a specific composition is used to be resolved in benzene and the resulting solution is applied to a substrate using an LB method to form a recording layer to prepare an optical recording medium. In this state, there is no anisotropy due to a polarizing ultraviolet visible absorption spectrum in a normal line direction in the surface of the recording layer and, when said recording layer is irradiated with ultrasonic rays, a chemical change is generated in the substrate and the material transparent at the beginning becomes a red colored material. When this colored material is irradiated with ultraviolet rays while heated to 35 deg.C, said colored material forms an association compound and this association compound is uniformly oriented in the surface of the recording layer by observation due to an optical microscope and the measurement of a polarizing visible absorption spectrum.
