Definitions
- Optical data carrier containing a hemicyanine dye in the information layer as a light-absorbing compound
- the invention relates to a write-once optical data carrier which contains a hemicyanic dye in the information layer as a light-absorbing compound, and to a method for its production.
- 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 media that are marked with blue ones
- Laser diodes in particular GaN or SHG laser diodes (360 - 460 ⁇ m) work 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 , and the application of the above-mentioned dyes to a polymer substrate, in particular polycarbonate, by spin coating or vapor deposition.
- 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.
- NA is the numerical aperture of the objective lens used. To receive one The highest possible storage density should be aimed at using the smallest possible wavelength ⁇ . 390 nm are currently possible on the basis of semiconductor laser diodes.
- 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 blurred 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.
- the invention therefore relates to an optical data carrier, comprising a preferably transparent substrate, optionally already coated with one or more reflection layers, on the surface of which an information layer which can be written on with light, optionally one or more reflection layers and optionally a protective layer or a further substrate or a cover layer is applied, which can be written and read with blue or red light, preferably laser light, the information layer containing a light-absorbing compound and optionally a binder, characterized in that at least one hemicyanine dye is used as the light-absorbing compound. Blue laser light is particularly preferred.
- the light-absorbing compound should preferably be thermally changeable.
- the thermal change preferably takes place at a temperature ⁇ 600 ° C., particularly preferably at a temperature ⁇ 400 ° C., very particularly preferably at one
- Such a change can be, for example, a decomposition or chemical change in the chromophoric center of the light-absorbing compound.
- a hemicyanine of formula I is preferred
- X 1 represents nitrogen or
- X 2 represents O, S, NR 2 or CR 3 R 4 ,
- R 1 and R 2 independently of one another represent Ci to C 16 alkyl, C 3 to C 6 alkenyl, C 5 to C 7 cycloalkyl or C 7 to C 16 aralkyl,
- R 3 and R 4 independently of one another represent d- to C 4 -alkyl or
- a together with X 1 , X 2 and the C atom bonded between them represents a five- or six-membered aromatic or quasi-aromatic heterocyclic ring which contain 1 to 4 heteroatoms and / or benzylated or naphthanellated and / or substituted by nonionic radicals can be,
