An optical information recording apparatus can maintain a stable recording
quality when recording information on an optical information recording
medium having a recording layer of a multilayer structure. An optical
information recording medium of a rotating type has a plurality of
recording layers each having an information recording area in which
information is recorded using a laser beam. An inner power calibration
area is provided in each of the recording layers at a location closer to
a center of rotation of the optical information recording medium than the
information recording area, and is used to perform a test write in an
optimum power control process to acquire an optimum recording power of
the laser beam. The outer power calibration area is provided at a
location farther from the center of rotation than the information
recording area, and is used to perform a test write in an optimum power
control process to acquire an optimum recording power of the laser beam.
