Abstract
A magnetic recording medium is provided with a textured surface comprising a landing zone, a data zone, and a transition zone having protrusions which gradually decrease in height and diameter in progressing from the landing zone to the data zone. The transition zone can be formed by laser texturing and controlling the peak power of a pulsed laser beam and/or rotating speed of the surface undergoing texturing.
