Definitions
- Optical data carrier containing a light-absorbing compound with several chromophoric centers in the information layer
- the invention relates to a write-once optical data carrier which contains a light-absorbing compound in the information layer with at least two identical or different chromophoric centers, as well as a process for its production and the application of the above-mentioned dyes to a polymer substrate, in particular polycarbonate, by spin coating or vapor deposition.
- the write-once optical data carriers using special light-absorbing substances or their mixtures are particularly suitable for use in high-density writable optical data storage devices that work with blue laser diodes, in particular Ga ⁇ or SHG laser diodes (360 - 460 nm) and / or for use with DVD-R or CD-R discs that work with red (635 - 660 nm) or infrared (780 - 830 nm) laser diodes.
- the next generation of optical data storage media - the DVD - is currently being launched on the market.
- the storage density can be increased by using shorter-wave laser radiation (635 to 660 nm) and a higher numerical aperture ⁇ A.
- the recordable format in this case is the DVD-R.
- the spot size scales with the laser wavelength ⁇ / ⁇ A.
- NA is the numerical aperture of the objective lens used.
- the aim should be to use the smallest possible wavelength ⁇ . 390 nm are currently possible on the basis of semiconductor laser diodes.
- the 780 nm wavelength of the CD-R lies at the foot of the long-wave flank of the absorption peak of the dye
- the red wavelength 635 nm and 650 nm of the DVD-R lies at the foot of the short-wave flank of the absorption peak of the dye.
- the recordable information layer made of light-absorbing organic substances must be as amorphous as possible
- the amorphous layer of light-absorbing substances should preferably have a high heat resistance, since otherwise further layers of organic or inorganic material, which are applied to the light-absorbing information layer by sputtering or vapor deposition, are diffused by diffusion Form interfaces and thus adversely affect reflectivity.
- a light-absorbing substance with too low heat resistance at the interface to a polymer carrier can diffuse in it and in turn adversely affect the reflectivity.
- An excessively high vapor pressure of a light-absorbing substance can sublimate the above-mentioned sputtering or vapor deposition of further layers in a high vacuum and thus reduce the desired layer thickness. This in turn leads to a negative influence on the reflectivity.
- the object of the invention is accordingly to provide suitable compounds which meet the high requirements (such as light stability, favorable signal-to-noise ratio, damage-free application to the substrate material, etc.) for use in the information layer in a write-once optical data carrier, in particular for high-density writable optical media Data storage formats in one
