    摘要: A target surface of a tape-shaped substrate of an oxide superconductor with an intermediate layer formed on this target surface and an oxide superconductor thin film is polished by causing the tape-shaped substrate to continuously run. The polishing step includes an initial polishing process for carrying out random polishing of the target surface and a finishing process that is carried out after the initial polishing process for forming grooves on the target surface along the running direction of the substrate. The intermediate layer has an in-plane directionality of 7° or less. The tape-shaped substrate is fabricated by rolling nickel, a nickel alloys or stainless steel.

    摘要: Diamond clusters are used as a polishing material of free abrading particles, each being a combination of artificial diamond particles having primary particle diameters of 20 nm or less and impurities that are attached around these diamond particles. The density of non-diamond carbon contained in the impurities is in the range of 95% or more and 99% or less, and the density of chlorine contained in other than non-diamond carbon in the impurities is 0.5% or more and preferably 3.5% or less. The diameters of these diamond clusters are in the range of 30 nm or more and 500 nm or less, and their average diameter is in the range of 30 nm or more and 200 nm or less. Such polishing material is produced first by an explosion shock method to obtain diamond clusters and then removing the impurities such that density of non-diamond carbon contained in the impurities and density of chlorine contained in other than non-diamond carbon in the impurities become adjusted.

    摘要: A glass substrate for perpendicular magnetic recording, having a surface with an average surface roughness of 2.0Å or less and surface height variations of 1Å or less with wavelengths in the range of 0.05 mm-0.5 mm in both radial and circumferential directions, is produced by rotating a glass substrate, supplying polishing slurry containing a specified amount of abrading particles of artificial diamond on its surface, pressing a polishing tape on the surface and causing this polishing tape to travel in a direction opposite to the direction of rotation of the glass substrate.

    摘要: A cleaning tape has a base tape made of a synthetic resin and a cleaning layer formed on a surface of this base tape. The cleaning layer has a binding agent and a large number of spherical particles dispersed in the binding agent in a single particle layer. Such a cleaning tape is capable of removing very small unwanted protrusions and particles on the surface of a target object such as a magnetic hard disk without forming scratches.
