Patent ID: 7746741

Claim:
An information recording apparatus comprising: a recording device for recording record information, by irradiating laser light having a predetermined power, onto an information recording medium on which pre-information for controlling the recording of the record information is recorded in advance; a controlling device for controlling said recording device to record the record information with such the power that first reproduction quality, which is reproduction quality of the pre-information, satisfies a predetermined first reference, wherein said controlling device controls said recording device to record the record information with such the power that the first reproduction quality satisfies the first reference, on the basis of correlation information indicating a correlation between the power and the first reproduction quality; and a generating device for generating the correlation information, by controlling said recording device to record test information for test recording onto the information recording medium while changing the power, and by measuring the first reproduction quality of the pre-information recorded in advance in a recording area in which the test information is recorded; wherein said recording device records the generated correlation information onto the information recording medium.
