MAGNETIC DISK
PURPOSE:To reduce variation in the attracting force between the disk and a head and to prevent demagnetization by roughening the area to be used for contact-start-stop (CSS) in the substrate surface of the magnetic disk with a uniform pitch and making the rugged pattern of same height.

| description | PURPOSE:To reduce variation in the attracting force between the disk and a head and to prevent demagnetization by roughening the area to be used for contact-start-stop (CSS) in the substrate surface of the magnetic disk with a uniform pitch and making the rugged pattern of same height. CONSTITUTION:At least the area for contact-start-stop (CSS) in the substrate surface of a magnetic disk is roughened with a uniform pitch and made to have the rugged pattern of same height. This roughening process is performed by use of cutting tools such as that made of diamond or material of similar hardness to make the rough surface of a uniform pitch and the roughness of same height. Thereby, the contact area to a magnetic head slider is made constant at any position of the magnetic disk surface. Thus, variation in the attracting force to a head depending on the position or demagnetization due to local stress concentration can be avoided. |
