Abstract

The invention relates to an optical recording media, in particular to the optical recording media that applies a method used for recording information by generating a new substance that has different reflectance with the circumstance in a recording layer when laser bean is used for irradiating. The optical recording media of the invention comprises a baseboard, a reflecting layer that is arranged on the baseboard, is adjacent to the baseboard and is reflected to enter laser beams by reflection and an information recording layer that is arranged above the reflecting layer. The information recording layer comprise: a first recording layer that selects an element of an element group that consists of Si, Ge, C, Sn and Zn as a main element and has the atomic percent of over 50 and a second recording layer that takes Au as a main element and has the an atomic percent of over 50. The optical recording media of the invention can not only record data at high density but also have very high stability and recording sensitivity when recording the data.

Description

technical field [0001] The present invention relates to an optical recording medium, in particular to a write-once optical recording medium capable of improving recording stability and densely recording data. With the advent of the multimedia era in which video, audio, and computer data information of moving images and still images can be integrated, packaged media of various optical discs such as CDs and DVDs are widely used. Recently, attempts are being made to widely apply optical recording media to recording media for mobile phones, digital cameras, broadcasting, and movies. In the future, in the next generation of media, this trend will become more apparent. Background technique [0002] This optical recording medium includes a read-only optical recording medium (Read-only memory: ROM), a recordable optical recording medium that can only record information once, and a rewritable (Rewritable) optical recording medium that can be repeatedly read, written and erased. ) o...
