Information recording apparatus and method, and computer program product

摘要

An information recording apparatus is provided with: a recording device for recording information into recording areas of an information recording medium by irradiating laser light; a reference-output-value holding device for holding a reference-output-value of the laser light for recording the information into the recording areas; an estimating device for estimating an output value of the laser light which was irradiated in the past in an already-recorded-area in which the information is already recorded; and a controlling device for controlling said recording device to irradiate the laser light onto the already-recorded-area with an output value larger than the reference output value if the estimated output value is larger than the reference output value.
