摘要： An evaluation method that can easily evaluate properties of a carbon protective film and a lubricant on a magnetic-disk surface or particularly, an evaluation method of a magnetic disk in which the properties of the magnetic-disk surface can be evaluated accurately so that a strict demand for interactions between the magnetic-disk surface and a head can be met is provided. In a state in which an element portion of the magnetic head provided with the head element portion that projects by thermal expansion is projected, after being brought into contact with a predetermined radial position on the surface of the rotating magnetic disk, the head is further made to perform seeking in a state in which the element portion is projected by a specified amount, whereby the properties of the carbon film or the lubricant formed on the magnetic-disk surface is evaluated.

摘要： An anisotropic texture is formed on a principal surface in the circumferential direction of the principal surface. The circumferential roughness of the principal surface increases from an outer circumferential section toward an inner circumferential section of the principal surface. The ratio [Ra-c/Ra-r] of the circumferential roughness (Ra-c) to the radial roughness (Ra-r) of the principal surface increases from the outer circumferential section toward the inner circumferential section.
