Definitions
- Optical data carrier containing a phthalocyanine dye as a light-absorbing compound in the information layer
- the invention relates to a write-once optical data carrier which can be used in the
- Information layer as a light-absorbing compound contains at least one phthalocyanine dye, and a method for its preparation.
- the write-once optical data carriers using special light-absorbing substances or mixtures thereof 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 - was recently launched.
- the storage density can be increased by using shorter-wave laser radiation (635 to 660 nm) and a higher numerical aperture NA.
- the write-once format 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 (cf. EP-A 519 395 and WO-A 00/09522).
- the writable information layer made of light-absorbing organic substances must be as amo ⁇ he 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 blurred by diffusion Form interfaces and thus adversely affect reflectivity.
- a light-absorbing substance with too low heat resistance at the interface to a polymeric carrier can diffuse in the latter 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 recordable optical media data storage
