Definitions
- Metal complexes as light-absorbing compounds in the information layer of optical data carriers are Metal complexes as light-absorbing compounds in the information layer of optical data carriers
- the invention relates to metal complexes, a process for their preparation, the azo compounds functioning as ligands of the metal complexes and their production, the coupling components on which the azo compounds are based and their production, and optical data memories which contain the metal complexes in their information layer, and the application of the dyes mentioned above 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 memories which work with blue laser diodes, in particular GaN or SHG laser diodes (360 - 460 nm) and / or for the Use with DVD-R (DVD-R, 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 NA.
- the recordable format in this case is the DVD-R.
- JP-A 11 043 481 and JP-A 10 181 206 It is for a high reflectivity and a high
- Modulation height of the readout signal as well as for sufficient sensitivity when use 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 and 650 nm of the DVD-R (DVD-R, DVD + R ) lies at the foot of the short-wave edge of the absorption peak of the dye.
- This concept is described in JP-A 02 557 335, JP-A 10 058 828, JP-A 06 336086, JP-A 02 865 955, WO-A 09 917284 and US-A 5 266 699 in the 450 nm range
- 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 other layers of organic or inorganic material, which are applied to the highly absorbing information layer by sputtering or vapor deposition, form blurred interfaces via diffusion and thus adversely affect the 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 therefore to provide suitable compounds that are high
