Title: Magneto-optical disk device
Inventor: SHIMIZU TADASHI
IPC: G11B11/10
Filed: 1989-07-10
Abstract: PURPOSE:To make optimum an external magnetic field to be impressed to a medium in the case of recording and erasing corresponding to a surrounding temperature and to reduce an adverse influence by the heat generation of the coil to the medium by arranging a heat sensitive element near an external magnetic field generating means. CONSTITUTION:A heat sensitive element 20 is fitted near a coil 8 for external magnetic field generation. This heat sensitive element 20 is bimetal and displaced in an optical axial direction with a supporting point 21 as a center at a high temperature, for example, at 50 deg.C. Therefore, a distance between a medium 17 and a coil 8 is separated. Accordingly, since a current to flow to the coil 8 is same, the intensity of the magnetic field is naturally decreased near the recording layer of the medium 17 when the distance is prolonged. Thus, since the intensity of the magnetic field near the recording layer of the medium 17 can be changed corresponding to the temperature, the adverse influence to be applied to the medium 17 by the heat generation of the coil 8 especially at the time of the high temperature can be extremely reduced.

Title: Optical sample measuring method
Inventor: SATO YASUSHI
IPC: G01N21/17
Filed: 1989-07-10
Abstract: PURPOSE:To accurately and easily measure a sample by selecting the material of a substrate so that the refractive index of the sample and that of the substrate satisfy a specific formula. CONSTITUTION:Incident light 3 is divided to surface reflected light 4 reflected by a surface S1 of a sample 1 and transmitted light 5 pepentrating the sample 1. This transmitted light 5 is divided to boundary surface reflected light 6 reflected by a boundary surface S2 between the sample 1 and the substrate 2 and transmitted light 7 penetrating the substrate 2. When the sample 1 is an approximately transparent thin film to have a low reflection factor, the quantity of the transmitted light 5 to the sample 1 increases considerably. The material of the substrate 1 is so selected that a refractive index n1 of the sample 1 and a refractive index n2 of the substrate 2 satisfy an inequality, and measurement is performed. Since refractive indexes n1 and n2 are relatively close, most of transmitted light 5 penetrates the substrate 2 as transmitted light 7. Consequently, the quantity of reflected light 6 is relatively reduced and is suppressed to <=20% of reflected light, and adverse influence of reflected light 6 upon measured data is eliminated.
