ABSTRACT:
A magnetic recording medium is formed with a laser textured glass or glass-ceramic substrate. The use of a pulsed, focused laser light beam, such as a CO.sub.2 derived laser light beam, enables the formation of an accurately textured landing zone on a glass or glass-ceramic substrate which is substantially replicated on subsequently applied layers.
