摘要： 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.

摘要： A method of initializing a phase transformation-type optical disk. The initialization method includes the steps of: (a) preparing a phase transformation-type optical disk in which a first dielectric layer, a recording layer including a small amount of crystalline structure in a major amorphous structure, a second dielectric layer and a reflective layer are sequentially deposited on a substrate; (b) irradiating a high power laser beam, which is enough to heat the recording layer to a temperature above its melting point, onto the optical disk, thereby transforming the crystalline structure in the recording layer into an amorphous structure; and (c) irradiating a lower power laser beam, which is capable of heating the recording layer to a temperature range above a recrystallization temperature and below its melting point, onto the optical disk, thereby transforming the amorphous structure of the recording layer into the crystalline structure.
