ABSTRACT:
The substrate of a magnetic recording medium is laser textured employing a fiber-optic laser delivery system. Fiber optic cables are optically linked at one end to a laser light beam source, and at the other lens to a microfocusing lens. The use of a fiber optic cable delivery system facilitates alignment and reduces maintenance.
