ABSTRACT:
An information recording apparatus for recording information on a multi-layered optical information recording medium having a recording material, which has light reaction property and which changes quality due to heat generated by an irradiated light, and having an altered layer in which the recording material is already altered and a non-altered layer in which the recording material is not yet altered alternately existing in plurals is provided. The information processing device includes a light source for emitting a recording light having a predetermined wavelength; a focal position control unit for controlling a focal position of the recording light emitted from the light source; and an objective lens, arranged at a post-stage of the focal position control unit, for collecting the recording light; wherein the recording material at the focal position is altered through heat by the recording light to record information on the recording medium as a recording mark.
