Description of Related Techniques In recent years, there have been many researches and developments on increasing the recording capacity of a disc-shaped optical recording medium (hereinafter referred to as " optical disc "). As a method of increasing the amount of information per unit area, a method of forming a recording layer into a multilayer structure may be adopted. For a read-only DVD (digital video disk) with two recording layers, the amount of information per unit area is approximately twice the number of DVDs with a single recording layer. The above D VD is a read-only DVD disc. The development of information recording media that allows users to record / reproduce information has flourished. Regarding the technology of a user-recordable optical recording medium compatible with DVD-R OM, a write-once optical recording medium (DVD-R) having a recording layer combined with an organic coloring material has been developed. In addition, an optical recording medium (DVD-RAM) incorporating a phase-change material and allowing information to be written most times has been developed. Each of these media has standards. Because the DVD-R has a reproduction function compatible with the DVD-ROM player, the written information can be reproduced by the DVD-ROM player. This DVD-R having only a single recording layer is not satisfactory in comparison with a D V D having two recording layers due to its smaller capacity.

The track grooves are 0.74 micrometers, the ratio of the width of each groove to the width of the land mass is 0.54, and the depth of each groove is 150 nm. Thereafter, a recording layer 110 composed of an organic coloring material film is formed on the surface of the first substrate 107 having grooves 108 and grooves 1009 formed thereon. The organic coloring material is NK — 4 2 8 8 (made of a light-sensitive coloring material of N i h ο η) having a structure in Chemical Formula 2. When the first substrate 107 is rotated at 2000 rpm, the NK-4288 tetrafluoropropanol solvent (0.4 wt%) is rotated and covered to form an organic coloring material film. The organic coloring material film is formed on the entire surface of the first substrate 107, regardless of whether it is only the regenerable area 1 2 0 and the write-permitted area 1 2 1. The organic coloring material film formed on the writing allowable area 1 2 1 serves as the recording layer 1 1 0.
