Laser texturing apparatus employing a rotating mirror

摘要

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.
