    摘要: A magnetic recording medium which is improved in durability by having smooth runability and high wear resistance, is obtained by forming a metal oxide film including CoO and a lubricant film of alkyl silane compound on the thin metal film type magnetic recording medium of CoCr or the like.
    The metal oxide film is a thin film including metal oxide of mainly Co, and the alkyl silane compound is composed by a linear or branched alkyl chain and silyl group. So, there is such synergetiv effect of combination of improved wear resistance owing to the metal oxide film and improved frictional performance of the alkyl silane compound having large bonding strength with the metal oxide that the magnetic recording medium having improved durability is realized.

    摘要: The present invention provides aligned fine particles(30) that are aligned on a substrate(32). An organic coating film(31) is bonded to surfaces of the fine particles(30) is formed on the surfaces of the fine particles(30). An organic coating film(33) bonded to a surface of the substrate(32) is formed on the surface of the substrate(32). The organic coating film(31) on the surfaces of the fine particles(31) is bonded(34) to the organic coating film(33) on the surface of the substrate(32), whereby the fine particles(31) are immobilized and aligned on the substrate(32). Thus, it is possible to align the fine particles(31) of a nanometer scale in a specific direction. When fine magnetic particles are used, a magnetic recording medium for high recording density can be obtained, and a high-density magnetic recording/reproducing apparatus can be provided.
