Abstract: Indolestyryl compounds and use thereof for a high density recording media and method for fabricating the same. The indolestyryl compounds exhibit strong absorbance in the visible light region (400˜700 nm) of the spectrum, resistance to heat and light, high light sensitivity, and excellent solubility, resulting from their special chemical configuration. Furthermore, the indolestyryl compounds can be used as recording layer materials in high density recording media for matching a reading laser wavelength and enhancing the reflective index and carrier-to-noise ratio (CNR) of the high density recording media. Accordingly, the recording sensitivity and the readout characteristics of high density recording media comprising the indolestyryl compound according to the present invention can be improved.

Abstract: A manufacturing method of cover layer of optical information storage media is disclosed. A plate and a substrate having a signal structure or recording layer are provided, a polymer resin is applied on the substrate. The plate is made to come in contact with the radiation-setting resin and then the radiation-setting resin is compressed against the substrate. The resulting structure is placed on a rotatable table and the rotatable is rotated. A radiation-setting resin layer with a uniform thickness is formed. The radiation-setting resin layer is illuminated by a UV light to harden the radiation-setting resin layer. Next, the plate is separed from the radiation-setting resin layer while the radiation-setting resin layer remain adhered to the substrate. The hardened radiation-setting resin layer serves as a cover layer.
