Definitions
- Optical data carrier containing a xanthene dye in the information layer as a light-absorbing compound
- the invention relates to a write-once optical data carrier, which in the
- Information layer as a light-absorbing compound contains a xanthene dye, and a process for their preparation.
- the write-once optical data carriers using special light-absorbing substances or their mixtures are particularly suitable for use with high-density writable optical data storage devices that work with blue laser diodes, in particular GaN 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, as well as the application of the above-mentioned dyes to a polymer substrate, in particular polycarbonate
- 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 NA.
- the recordable format in this case is the DVD-R.
- the patent literature describes dye-based writable optical data memories which are equally suitable for CD-R and DVD-R systems (JP-A 11 043 481 and JP-A 10 181 206).
- JP-A 11 043 481 and JP-A 10 181 206 For a high reflectivity and a high modulation level of the readout signal, as well as for a sufficient sensitivity when writing, use is made of the fact that the IR wavelength 780 nm 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 or 650 nm of the DVD-R lies at the foot of the short-wave flank of the absorption peak of the dye.
- the writable information layer made of light-absorbing organic substances must have a morphology which is as amorphous as possible in order to keep the noise signal as small as possible when writing or reading.
- the substances are applied by spin coating from a solution, by vapor deposition and / or sublimation, subsequent crystallization of the light-absorbing substances with metallic or dielectric layers in vacuum is prevented.
- 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
- 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 therefore 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 recordable optical media Meet data storage formats in a laser wavelength range from 340 to 680 nm.
- a high capacity optical storage medium containing xanthene dyes is known from EP-A-0 805 441.
- the claimed xanthene dyes can have up to four positive or negative excess charges and corresponding counterions.
- a proton or a metal, ammonium or phosphonium cation are described as cationic counterions.
- light-absorbing compounds from the group of xanthene dyes which contain at least two anionic groups and have at least one cation as counterion, which contains at least one specific conjugated ⁇ system with at least 6 ⁇ electrons, meet the requirement profile mentioned above can meet particularly well.
