Definitions
- the present invention relates to an optical recording medium using a trimethine dimer compound and capable of recording and reproducing at a higher density than before.
- FIG. 1 The general structure of DVD-R is as shown in FIG. 1.
- a recording layer 2, a reflective layer 3 and a protective layer (or adhesive layer) 4 are formed on a transparent resin substrate 1 having lands and groups. In some cases, a substrate 5 is further provided thereon.
- the transmission wavelength of one laser beam is 6 30 nm for high-density recording.
- the wavelength is shorter than in the case of ⁇ 68 0 nm and CD-R.
- dyes for organic dye-based optical recording media for such short wavelengths include trimethine compounds, azo compounds, porphyrin compounds, indigo, dioxazine compounds, coumarin compounds, perylene compounds, naphtholactam compounds, triflic compounds. Enilmethane compounds, subphthalocyanine compounds, dibenzopyran compounds, dipyrromethene compounds, etc. have been proposed.
- optical recording media using trimethine compounds are being investigated because of their excellent optical properties and high density.
- optical recording is also possible for DVD-R at 8x, 12x, or 16x faster than standard recording speed.
- a medium is desired.
- recording at high speed especially at speeds of 12x or higher, there is a problem of insufficient sensitivity due to the output limit of the recording laser, and thermal interference between recorded pits due to heat generated during pit formation. Problems such as increase and jitter deterioration have become apparent.
- JP-A-11-53761, JP-A-2000-108510, JP-A-2000-289335, etc. disclose trimethine compounds into which a nitro group is introduced, and JP-A-2002-52829 discloses specific compounds. Trimethine compounds in which a spiro ring is introduced at the position are disclosed, and there is a description that both have good sensitivity to the recording laser. However, there is no description regarding sensitivity at high speed recording and jitter deterioration due to thermal interference.
- JP-A-2003-231359, JP-A-2005-54150, and JP-A-2005-53875 disclose trimethine compounds in which a benzyl group is introduced at a specific position. Although there is a description that it corresponds to high-speed recording, there is no description about high-speed recording characteristics at 12 times or higher speed recording, and there is still room for improvement.
- Japanese Patent No. 3627892 discloses a dimer of cyanine, but the substituents are limited, and there is no description about high-speed recording.
