    摘要： An optical information recording medium is here disclosed which comprises a transparent substrate, a recording layer comprising an organic dyestuff on which information can be written by a laser beam, a reflective layer and a protective layer formed in this order on the substrate, the aforesaid optical information recording medium being characterized by containing a pit-edge control agent for the formation of recording pits, particularly a dyestuff thermal decomposition accelerator in the recording layer. By the addition of the pit-edge control agent, deviation properties and jitter properties can be remarkably improved, whereby a CD-R medium having a low error rate and good recording properties can be provided. In consequence, stable compatibility with a commercial CD player can be secured.

    摘要： There is provided with an optical recording medium comprising at least a dye-containing recording layer and a reflective layer laminated on a transparent substrate in this order which has a reflectance of 65% or higher, measured through the substrate, to a light beam having a selected wavelength (.lambda.1) of from 770 to 830 nm and has a reflectance of 15% or higher to a light beam having a selected wavelength (.lambda.2) of from 630 to 690 nm and which is recordable and reproducible with a laser beam having the wavelength of .lambda.1 and being reproducible with a laser beam having the wavelength of .lambda.2. In addition, the recording layer has a dye A having the absorption maximum at the wavelength shorter than 630 nm mixed with a dye B having the absorption maximum at the wavelength of from 630 to 900 nm. Alternatively, an interference layer is provided along with the recording and reflective layers. The recording layer is based on a phthalocyanine dye while the interference layer is based on an inorganic dielectric, a polymer, or an azo dye. The requirements for the interference layer are also provided.

    摘要： The present invention relates to an optical recording medium having a recording layer, a reflective layer and a protective layer on a substrate, wherein a quinophthalone compound represented by the following formula (1) is contained in the above recording layer. The use of the quinophthalone compound or a mixture of the quinophthalone compound and a photoabsorbing compound having an absorption maximum in a wavelength falling in a range of 550 to 900 nm in the recording layer makes it possible to provide an interchangeable optical recording medium not only capable of recording and reproducing with a laser having a wavelength falling in a range of 480 to 600 nm, but is also capable of recording and reproducing with red lasers having wavelengths of 630 nm and 680 nm and a near infrared laser having a wavelength of 780 nm. ##STR1##
