| titleOfInvention | Method of measuring characteristics of magnetic disk medium and magnetic disk medium |
| abstract | (57) Abstract: A characteristic measuring method capable of appropriately evaluating characteristics of a flexible magnetic disk medium using a quasi-floating type magnetic head, and an excellent method using the characteristic measuring method. Provided is a magnetic disk medium having characteristics. The magnetic disk medium is rotated at a predetermined number of revolutions, and the magnetic head is arranged at a predetermined angle with respect to a rotational tangential direction while the magnetic disk medium is sought in a radial direction by the magnetic head, By measuring the frictional force between the magnetic head and the magnetic disk medium, the frictional force is reduced to 12 mN or less for the former and 15 mN for the latter. Hereinafter, the above problem is solved by setting the center plane average surface roughness Ra to 4 nm or less, and setting the C / Fe peak ratio when the surface is measured by Auger electron spectroscopy to 30 to 120. |
