  • Patent number: 5664985
    Abstract: A method and apparatus is disclosed for texturizing magnetic storage disks. The disk texturizing apparatus utilizes a combination of servomotors for rotating the disk and oscillating the disk towards and away from a texturizing media. The servomotors are controlled by a closed-loop control system which monitors and synchronizes the angular and linear position of the disk. Through such control, the disk rotation speed may be modulated in conjunction with the linear oscillation, thereby allowing a higher degree of triangularity in the texturization pattern. A pattern generation system and a graphical user interface for specifying, modeling, generating, modifying and displaying disk texturizing patterns are also disclosed. The texturizing pattern may be displayed in polar plot and linear plot form so that the user can more easily visualize and design the texturizing pattern.
