A servo patterned disk and method for making the disk. The disk substrate is made of a rigid material such as glass, plastic, or metal. The servo pattern is formed using a process wherein a high contrast mask of the servo pattern is made and then used to create a hologram template. The hologram template is then used to create a real image of the high contrast mask on the substrate surface from which substrate material is removed to form the servo pattern. The pattern can be generated in both sides of the disk if desired. |
