ABSTRACT:
Formation of laser texture features simultaneously on the target surfaces of each side of magnetic recording disk is facilitated by optical and mechanical components permitting excellent balance of optical power between each target surface, excellent matching of the radial position of laser texture features between each target surface, and excellent focusing of laser beams on each target surface. Polarization of the source laser beam may be used to controllably balance and direct a single source beam into individual beam paths for each target surface. Handling, automation complexity, and manufacturing time is thereby reduced.
