A phase change optical recording medium. A recording layer is formed on a substrate having a plurality of non-metal particles disposed therein uniformly. Consequently, phase change can occur not only in the interface between crystal and amorphous regions, but also the interface between the particles and the amorphous region.

The present invention provides a disk storage apparatus including a base, a transmission unit, an actuation unit, and a tray. The transmission unit is disposed on the base. The transmission unit is movably connected to the actuation unit. The tray is provided to support at least one disk. The tray and the transmission unit are movably connected to each other. The actuation unit drives the transmission unit to cause the tray to move relatively to the base.

The invention discloses an optical recording medium comprising a first substrate, a second substrate, a median layer and an adhesive layer. A plurality of Braille characters is formed on the second substrate by injection molding. The median layer is formed on the first substrate. The second substrate is adhered to the median layer by the adhesive layer. Accordingly, a visually-impaired person can easily identify the contents in the optical recording medium by touching the Braille characters on the second substrate.

A disc having a relief pattern and a transprint method thereof are provided. The transprint method for transprinting the relief pattern on a substrate of the disc includes the following steps. First, a transprint template is provided. A first surface of the transprint template has a complementary pattern corresponding to the relief pattern. Next, a pattern layer is formed on the substrate. Then, the transprint template is placed on and covers the pattern layer until the first surface of the transprint template closely contacts a second surface of the pattern layer, so that the relief pattern is formed on the second surface. Afterward, the pattern layer is cured by irradiation. Later, the transprint template is removed for exposing the second surface with the relief pattern.

Light emitting diodes are arranged in a matrix under an incident surface of a light guide panel. The incident surface includes a plurality of incident blocks arranged with each incident block respectively positioned beside a corresponding LED. Each incident block includes a plurality of surfaces having different normal vectors or curvature radiuses for scattering light emitted from the corresponding LED. A reflection film may be used to reflect light generated from the plurality of LEDs and a diffuser sheet may be positioned at one side of a light-exit surface of the light guide panel.

A method for forming a polarization film is disclosed. A polyvinyl alcohol, PVA film is provided. The PVA film is swollen, and then dyed and stretched in a solution, wherein the solution comprises iodine, potassium iodide, EDTA and calcium ions. The dyed PVA film is re-stretched, and the dyed PVA film is reacted with crosslink agent.
摘要:
A thin film. The thin film is fabricated by placing a thin film having a hydroxyl groups-containing surface in a water tank containing dicarboxylic acid and stretching the thin film.
摘要:
A carrier device used for carrying an optical disk in a manufacturing process is provided. The carrier device includes a base, a first supporting piece and a second supporting piece. The base includes a carrying area whose size is equal to that of the optical disk. The first supporting piece is protruded from the base and located at the center of the carrying area. The second supporting piece is disposed on the base and located in the carrying area. The second supporting piece is separated from the edge of the carrying area at a distance of more than or equal to one fourth of the radius of the carrying area.
