Definitions
- the present invention relates to an LTH (Low to High) recording type write-once optical recording medium having a recording layer containing an organic dye and capable of recording and reproducing data with light having a wavelength of 300 nm to 500 nm. More specifically, it is an LTH (Low to High) recording type write-once optical recording medium having a recording layer containing an organic dye and capable of recording and reproducing data with light having a wavelength of 300 nm to 500 nm. In addition, the present invention relates to a write-once type optical recording medium in which a light transmission layer can be formed in a single layer and the recording / reproducing characteristics are not deteriorated even when stored in a high temperature and high humidity environment.
- LTH Low to High
- optical recording media that have a recording layer containing a conventional organic dye material and can record and reproduce data with light having a wavelength of 300 nm to 500 nm
- the type optical recording medium had a two-layer light transmission layer. That is, the outer light-transmitting layer is a layer for preventing the optical recording medium from being scratched, as is the case with the light-transmitting layer of a write-once type optical recording medium having a recording layer containing an inorganic material.
- the inner light transmission layer absorbs and accepts the deformation of the recording layer due to the heat generation and expansion of the organic dye during data recording, and the change in reflectance is caused by the difference in the optical path length accompanying the deformation of the recording layer. It is intended to ensure the recording characteristics by inducing, and is formed of a soft and low elastic modulus material such as an acrylic resin or an adhesive.
- the write-once type optical recording medium in which the light transmission layer has a two-layer structure and the inner light transmission layer is formed of a soft and low elastic modulus material such as an acrylic resin or an adhesive is used at the time of data recording. Since the deformation of the recording layer due to the heat generation and expansion of the organic dye is absorbed by the inner light transmission layer, there is an advantage that almost no stress is generated in the optical recording medium.
- the light transmission layer has a two-layer structure, the cost of the optical recording medium increases. Therefore, even in a Blu-ray disc type write-once optical recording medium in which a recording layer is formed using an organic dye, an inorganic material is used. As with the Blu-ray Disc type write-once optical recording medium on which the recording layer is formed, it is desirable that the light transmission layer has a single layer structure.
- An azo metal complex dye having a specific molecular structure has been found as an organic dye capable of obtaining an excellent Blu-ray disc type recordable optical recording medium. *
- a Blu-ray disc type write-once optical recording medium in which a recording layer is formed using such an azo metal complex dye
- a Blu-ray disc type write-once light in which a recording layer is formed using a conventional organic dye Although it is possible to improve the recording / reproducing characteristics as compared with the recording medium, it is still difficult to completely absorb and accept the deformation of the recording layer at the time of data recording by the light transmission layer having a single layer structure.
- the stress generated during the formation of the recording pits remains in the optical recording medium, and when the optical recording medium on which the data is recorded is stored in an environment of high temperature and high humidity, a part of the recording layer is caused by the residual stress. There is a problem that the recording and reproducing characteristics deteriorate due to peeling.
- the present invention is an LTH (Low to High) recording type write-once optical recording medium having a recording layer containing an organic dye and capable of recording and reproducing data with light having a wavelength of 300 nm to 500 nm.
- the light transmission layer can be constructed in a single layer, and even when stored in a high-temperature and high-humidity environment, the recording layer can be prevented from peeling, and the deterioration of recording and reproducing characteristics can be reduced. It is an object to provide a type optical recording medium.
- the present inventor has peeled off the recording layer even in the case of storing an optical recording medium on which data is recorded in a high temperature environment but not in a high humidity environment. It was found that peeling occurred only when stored in a high humidity environment. Furthermore, as a result of repeated research, this phenomenon is recorded when the optical recording medium is stored in a high humidity environment because the above-mentioned azo metal complex dye contained in the recording layer has a high affinity with water. The azo metal complex dye contained in the layer retains water molecules, the binding property between the recording layer and the protective layer is reduced, and a part of the recording layer is peeled off due to the residual stress generated during recording pit formation.
- the recording layer is formed by mixing a dye having high water resistance with the azo metal complex dye forming the recording layer to improve the water resistance of the recording layer and to reduce the affinity with water. It has been found that even when the optical recording medium is stored in a high humidity environment, a part of the recording layer can be prevented from being peeled off by suppressing a decrease in binding property between the protective layer and the protective layer.
