Abstract
An optical disc for an optical near-field recording having a surface with a textured structure formed with a plurality of bumps and craters, and a method of manufacturing the optical disc. An optical flying head has a slider which contacts the bumps when in a parking zone (non-moving state) so that a contact area between the optical disc and the optical flying head is reduced. Accordingly, a stiction force is reduced, so that the wear and damage to the optical disc having the textured structure and to the optical flying head are minimized.
