摘要： A glass substrate for perpendicular magnetic recording, having a surface with an average surface roughness of 2.0 Å or less and surface height variations of 1 Å 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： In a magnetic head a single-crystal Mn--Zn ferrite is employed as a core material, and cut-away parts in the vicinities of a gap are filled with a glass the contraction rate of which is lower than that of the ferrite. A principal magnetic circuit-forming plane of the core is brought into agreement with the {1 1 0} plane of the ferrite, while an angle .theta. defined between the direction within the {1 1 0} plane of the ferrite and a gap forming plane is made 5.degree.-40.degree. or 80.degree.-120.degree.. The magnetic head thus constructed exhibits very favorable write and read characteristics.

摘要： Polishing particles are made of artificial diamond produced by a shock method, having density of 3.0-3.35 g/cm3 and including secondary particles with average particle diameter of 30 nm-500 nm. Such polishing particles are produced by firstly obtaining a product containing artificial diamond by a shock method, then subjecting this product to an acid treatment by using one or more strong acids such as concentrated sulfuric acid, concentrated nitric acid and concentrated hydrochloric acid to thereby remove impurities from and wash the product, thereafter subjecting the product to a classification process to thereby separate artificial diamond of a first kind having secondary particles with particle diameters of 30 nm-500 nm and artificial diamond of a second kind having secondary particles with particle diameters in excess of 500 nm and selecting artificial diamond of a third kind having density of 3.0-3.35 g/cm3 out of the artificial diamond of the first kind. It is the artificial diamond of the third kind that is to be used as the diamond polishing particles.

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.

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.
