Abstract: PURPOSE:To improve protection of a recording layer and consequently to improve is weatherability and long-term stability by forming 1st an 2nd protective film layers to have boron nitride films contg. boron nitride respectively varying in crystal structure. CONSTITUTION:A 1st layer 12 has a boron nitride film layer contg. boron nitride h-BN resembling hexagonal graphite and a 2nd protective film 14 has the boron nitride film layer contg. boron nitride c-BN having the sphalerite crystal structure of a cubic crystal system, respectively. The boron nitride film layers are chemically excellent in stability and therefore excellent in the protective property of the recording layer. The function to protect the recording layer is thus improved and the weatherability and stability are improved as well. The c-BN has a high thermal conductivity, and therefore diffuses heat within the protective film layer 14. An amorphous state of a small recording spot size is easily obtd. and C/N is improved. Generation of imperfect erasing is simultaneously obviated and the erasing ratio is improved.
