Abstract
A method for calibrating a recording condition in an information recording unit includes: heating a recorded data pattern recorded on the information recording medium; reproducing the recorded data pattern after the heating, to measure a reproduced-signal quality; and determining a recording condition based on the measured reproduced-signal quality.

A method for calibrating a recording condition in an information recording unit that performs recording on an optical information recording medium for which a mark is recorded by optical beam irradiation, said method comprising:
- heating a first recorded data pattern recorded on the information recording medium;
- reproducing said first recorded data pattern after said heating, to measure a reproduced-signal quality;
- and
- determining a desired recording condition based on the measured reproduced-signal quality.
An information recording unit that records a mark on an information recording medium by using optical irradiation, comprising:
- a parameter calibration unit that heats a first recorded data pattern recorded on the information recording medium, reproduces said first recorded data pattern after said heating, to measure a reproduced-signal quality, and determines a desired recording condition based on the measured reproduced-signal quality.
