An optical information recording apparatus, an optical information recording method, and an optical information recording medium that enable information signals to be recorded precisely by determining recording conditions such as recording power, edge positions of recording pulses, and the like suitably before recording information signals. An edge test signal generation circuit 4 supplies a test signal for optimizing edge positions of recording pulses. A system control circuit 32 calculates an average of intervals between edges in test signals reproduced from the plurality of sectors and determines the difference between the average and an original interval between edges in the test signal, thus determining a compensation volume for edge positions. A power test signal generation circuit 33 then supplies a test signal for optimizing the recording power. The system control circuit 32 then calculates the recording power value that allows the bit error rate to be a certain threshold, and based on this value sets the recording power to the proper value.
