Abstract: In a track control method for marking a label side of an optical disc, a data side of the optical disc is first oriented to an optical head. A light beam is then emitted and a sled carrying the optical head moves. A series of moving distances of the sled are calculated according to the light beam reflected by the optical disc, which are then recorded in a memory. The optical disc is then flipped to have the label side face the optical head, and the shift of the optical head is controlled to mark on tracks of the label side according to the series of moving distances recorded in the memory.

Abstract: A method of fabricating a reflective type LCD, having the steps of: (a)providing a substrate; (b) forming a polymer resin layer on the substrate; (c) forming a positive-type photoresist layer on the polymer resin layer, wherein the upper surface of the photoresist layer has a convex/concave profile; and (d)performing a dry etching process to completely remove the photoresist layer and partially remove the polymer resin layer so as to shape the upper surface of the polymer resin layer into a convex/concave profile.
