Abstract:
1. An optical information recording apparatus for recording information, the optical information recording apparatus being configured to form recording marks and spaces onto an optical information recording medium having a recording layer whose reflectivity in recording changes from low to high, the recording layer having a predetermined absorption ratio to a light whose wavelength is 405 nm, the recording marks and spaces being formed by irradiating a laser of adjacent range wavelengths including said wavelength of 405 nm, the optical information recording apparatus comprising: a setting unit to respectively set a write power to form said recording marks, a space forming power whose power value is less than said write power, to form said spaces, and a pulse width of a cooling pulse whose power value is less than said space forming power and which is output immediately after a last pulse when said recording mark is formed; and a unit to record information onto said optical information recording medium according to said setting unit,
