Title: Magnetic recording medium
Inventor: SUMITA KUNYU
IPC: G11B5/65
Filed: 1988-03-30
Abstract: PURPOSE:To improve durability by providing an underlying layer having the hardness larger than the hardness of a thin magnetic metallic film layer which is a recording layer between this thin magnetic metallic film layer and a flexible nonmagnetic substrate. CONSTITUTION:The underlying layer 3 is continuously formed in a gaseous mixture atmosphere composed of oxygen and argon in a reactive sputtering method using a Co-Cr target on the flexible nonmagnetic substrate 2 consisting of a long-sized polyester film. The thin magnetic metallic film layer 4 consisting of C-Cr which serves as a recording layer is formed under specified conditions on the respective underlying layers 3 and oil of a fluorine system is coated as a lubricating layer 5 on the respective thin magnetic metallic film layers 4. Stress concentration is relieved and the permanent deformation of the magnetic recording medium is obviated if the layer having a high Young's modulus exists between the flexible substrate and the thin metallic film layer in such a manner. The permanent deformation is thereby prevented and the durability is improved.

Abstract: PURPOSE:To obtain stable excellent characteristics when the sum of photocurrents in a plurality of light-receiving regions is required by forming an insulating film of a uniform thickness and an antireflection film in a plurality of the liglht-receiving regions and on the surfaces of dead zones among these light-receiving regions. CONSTITUTION:An N-type semiconductor region 2 having low concentration is shaped onto an N-type semiconductor substrate 1 having high concentration, P-type semiconductor regions 3a, 3b constituting light-receiving regions A1, A2 and having high concentration are formed into the region 2, a thermal oxide film 4 is shaped in equal thickness, and an antireflection film 5 is formed onto the surface of the thermal oxide film 4. When the surface is scanned while being irradiated with a light spot, photocurrents are changed, and photocurrents I (A1) in one light-receiving region A1 are reduced while photocurrents I (A2) in the other light-receiving region A2 are increased in a dead zone section. When the sum I (A1+A2) of photocurrents in two light-receiving regions A1, A2 is acquired, however, a level in the dead zone is equalized to levels in each light-receiving region A1, A2, and flat characteristics are obtained. Accordingly, when the sum of photocurrents is required, fixed photocurrents can be output regardless of the incident position of light.

That is, the cooling is controlled so as to make small the temperature distribution in the direction of thickness at the martensitic transformation range. According to this method, the unevenness or degradation of quality of material due  to the minglement of imperfect quenched structure, are excluded, and the quenching crack is perfectly prevented.
