Abstract: A recording apparatus characterized in that comprising a firmware configured to execute the following operation: performing a recording operation onto a rewritable optical recording medium with a recording speed selected from one of a plurality of recording speeds for an one-time optical recording medium; wherein the recording layer of the rewritable optical recording medium comprises at least four elements from Ge, In, Sb, Te, and Sn, wherein the component proportion of Sb/Te is ranged from 3 to 8, and the thickness of the recording layer is ranged from 3 nm to 25 nm.

Abstract: The present invention is related to an optical recording media having a printable layer with high specular gloss. The optical recording media comprises a first ink-absorbing layer formed on an outermost layer at an opposite side of a recording/reading surface of the optical recording media; and a second ink-absorbing layer formed on an inner side of the first ink-absorbing layer. A surface of said first ink-absorbing layer is printed with inks of colors of cyan, magenta, yellow, black to have an average specular gloss value at 20 degree angle greater than or equal to 30GU, an average specular gloss value at 60 degree angle of the four colored inks greater than or equal to 70GU, and an average specular value at 85 degree angle of the four colored inks greater than or equal to 88GU.

Abstract: An optical recording media includes a substrate, a cap layer opposite to the substrate, at least one first stacked recording structure, at least one second stacked recording structure, and a space layer. The first stacked recording structure including a first recording layer disposed between the substrate and the cap layer and a reflective layer disposed between the substrate and the first recording layer is disposed between the substrate and the cap layer. The second stacked recording structure including a second recording layer disposed between the substrate and the cap layer and an Nb2O5 interface layer disposed between the substrate and the second recording layer is disposed between the substrate and the cap layer. The spacer layer is disposed between the first and second stacked recording structures, the first stacked recording structures, and the second stacked recording structures. One of the first stacked recording structures is disposed directly on the substrate.

Abstract: A method for improving read stability of optical recording medium is disclosed. In the method, the thickness of a recording layer of an optical recording medium is adjusted to control the disc absorptivity, and the recording layer thickness is matched with a power difference between a laser write power (Pw) and a laser erase power (Pe), so as to control the optimal laser power for irradiating and accordingly changing the optical properties of the recording layer. It is found that by using properly increased recording layer thickness corresponding to a given disc absorptivity, and properly matching the recording layer thickness with a properly increased power difference, the read stability and recording characteristics of the optical recording media can be improved without significantly changing the layer structure and writing strategy of the optical recording medium.
