Patent ID: 7738337

Claim:
An optical information recording device for forming a recording pattern comprising a pit and a land onto an optical recording medium by irradiating a laser beam based on a recording pulse, the optical information recording device comprising: a recording apparatus configured to generate optimum conditions for a power and a phase of the recording pulse by a test recording onto the medium; a recording apparatus configured to detect recording states of a pit and a land formed by an actual recording onto the medium; a circuit configured to detect a power shift amount from the optimum condition based on the detected recording states; a circuit configured to detect phase shift lengths of the pit and the land based on the detected recording states; a circuit configured to derive correction amounts for the generated power and the generated phase of the recording pulse from the detected recording states; a circuit configured to correct the power and the phase of the recording pulse based on the derived correction amounts; a circuit configured to subtract an amount affected by the power shift amount from the detected phase shift length; a circuit configured to correct the optimum condition for the phase based on a phase shift length from which the amount affected by the power shift amount is subtracted; and a circuit configured to correct the optimum condition for the power based on the detected power shift amount.
