    摘要: A texture treatment for a carbon substrate of a magnetic disk or for a carbon overcoat layer of a magnetic disk is effective to prevent the generation of a stiction phenomenon between a magnetic head and the surface of a magnetic disk. The texture treatment for a carbon substrate or carbon overcoat of a magnetic disk involves the steps of: preparing the carbon disk surface; forming a catalytic material layer on the surface; and performing a heat treatment of the disks in an oxidizing atmosphere. Preferably, islands of catalytic material are formed on the surface by sputtering, and a laser heat treatment is used in an oxidizing atmosphere.

    摘要: A method of manufacturing a magnetic recording medium such as for a magnetic disc, in which a magnetic layer comprising a Co-based alloy is formed on a carbon substrate and a heat treatment is applied at a temperature of 250.degree. to 1450.degree. C. to improve the coercive force. Further, the squareness ratio is improved by applying the heat treatment under a magnetic field. Greater coercive force can be obtained by forming a Cr underlayer prior to the formation of the magnetic layer. Increased recording density of the magnetic recording medium can be realized by improving the coercive force and the squareness ratio in this way.

    摘要: In an optical fiber array (1) which has a V-groove substrate (2) formed in its surface (2a) with V-grooves (3) for arranging optical fibers, a plurality of optical fiber cores (61) fixedly bonded in each individual V-groove (3) of the V-groove substrate (2), and a pressure plate (4) fixedly bonded to surfaces of the optical fiber cores (61), an adhesive comprising a resin composition (component A) having an OH group after curing and a filler (component B) is used to fixedly bond the V-groove substrate (2), the optical fiber cores (61), and the pressure plate (4). This adhesive has a glass transition temperature that is somewhat lower than the ambient test temperature and possesses somewhat higher elasticity. Therefore, large internal stress does not occur in the adhesive even under conditions of high temperature and high humidity. Consequently, no peeling occurs as a result of moisture penetration since gaps cannot form between the pressure plate (4) and the adhesive.
