发明名称 OPTICAL INFORMATION RECORDING METHOD
摘要 PROBLEM TO BE SOLVED: To provide a method for performing stable CD player compatible recording, capable of providing high reflectance satisfying a CD standard, and a stable tracking servo characteristic before/after the recording, providing a sufficient degree of signal modulation, even in an EFM signal reproducing characteristic, and securing low jitter characteristic, and low crosstalk characteristic. SOLUTION: This method is for recording information on a single plate optical information recording medium composed of a recording layer, a metal reflection layer and a protective layer provided on a substrate having a groove formed, in a manner such that a tracking groove half value width is set in the range of 0.2 to 0.6 μm, and a groove inclination angle at the half value width part is set in the range of 25 deg. to 65 deg.. By having the recording layer irradiated with a laser light to execute recording, the substrate groove half value width of a recording pit formation part is expanded by 0.5 μm or more in a range up to 0.90 μm, or the half value width is expanded by 0.05 μm or more in a range up to 0.9 μm, and the substrate groove inclination angle of the recording pit formation part is changed by plus or minus 10 deg. or larger.
