Abstract: A method for fabricating an optical recording medium is provided. A dye layer is formed on a molded substrate by spin-coating. A reflection layer is formed on the dye layer by sputtering so that the optical disc has enough reflection rate. The dye layer comprises a cyanine type dye and an azo metal chelate compound selected from the formula (I): wherein M is a metal ion; R1 is a hydrogen atom, a linear or branched alkyl group containing 1 to 6 carbon atoms, amino group, alkyl amino group or toluidinyl group; R2 is a hydrogen atom, a hydroxyl group, a halogen atom, an ether group, an ester group or a linear or branched alkyl group containing 1 to 6 carbon atoms; R3 is a hydrogen atom or a linear or branched alkyl group containing 1 to 6 carbon atoms; R4 is a hydrogen atom, a halogen atom or a linear or branched alkyl group containing 1 to 6 carbon atoms; A1 is a heterocyclic derivative group constituted by carbon atoms and nitrogen atoms.

Abstract: A method and structure for intensifying track seeking signals from an optical disk, in particular, a recordable digital versatile disk (DVD-R). With the addition of an optical correction layer between a dye material layer and a reflection layer inside the DVD-R, track-seeking signals of the optical disk are intensified and recording quality of the optical disk is improved. The optical correction layer is a transparent or semi-transparent layer made from inorganic materials. The optical correction layer is formed over the dye material layer in a sputtering process.

Abstract: A hybrid dual-sided DVD. Recordable surfaces are respectively formed on each of the two sides thereof. Fabrication of the DVD utilizes the conventional steps of coating, gluing, sticking, and others, or uses other disc manufacturing techniques such as single-layered, two-to-one, or three-to-one to integrate a dual-sided DVD structure. The DVD conforms to one-time-only recordable, re-recordable, or other series types. The hybrid dual-sided DVD is able to carry un-rewriteable data on one side, while allowing an end user to record and/or re-record supplementary or complementary data on the reverse side, proving more convenient for information integration, delivery, and storage.
