ABSTRACT:
An apparatus and method for laser texturing of magnetic recording media are described. The apparatus includes an optical assembly, containing first and second mirrors, which are rotated and optionally shifted during a texturing operation. This optical assembly directs a pulsed laser beam onto a series of focused spots on the surface of a magnetic disk, creating a desired pattern of texturing while maintaining a constant focus of the beam at the surface of the disk.
