Abstract: An optical film and manufacturing method thereof are provided. The optical film includes a main body and a plurality of first microstructures. A plurality of micro bubbles is disposed inside the main body. The first microstructures are disposed on one side of the main body. The optical film can avoid light having smaller or reduced incident angle from being reflected by the first microstructures, therefore, as a result, the illumination brightness using the optical film can be enhanced.

Abstract: A read/write disc scratch prevention process involves having an injection comprised of resin, monomer, photosensitizer and catalyst mixed at a proper ratio evenly coated by means of an eccentric method on the data read/write surface of a disc, then the coated surface UV cured to transform compositions in the injection into a transparent film of given hardness, thus to form an effective scratch prevention for the data read/write surface of the disc and to provide longer service life of the disc by maintaining a neat and leveled data rear/write surface, and permitting to be done before burning the data into the disc for assurance of data writing accuracy and preventing scratch.
