    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 a motor portion of a linear actuator, a rear end cap and a front end protrusion, which are disposed respectively at the rear and front ends of a stator assembly, and which include rear and front bearings to rotatably support a rotor assembly, are formed by injection-molding simultaneously and integrally with a stator support member which fixedly supports constituent members of the stator assembly, whereby the stator assembly, the rear end cap, and the front end protrusion can be coaxially aligned to one another with a high degree of precision thus improving the assembling precision of the motor portion. Also, since the front bearing can be attached to the front end protrusion before an output shaft is attached, the rotation characteristic of the rotor assembly can be evaluated before the output shaft is attached.
