Patent ID: 7693015

Claim:
An optical information recording device for forming pits and/or spaces on an optical recording medium by irradiating a laser beam based on a recording pulse stream having a first recording pulse comprising a top pulse alone and a second recording pulse comprising the top pulse and a succeeding pulse, the optical information recording device comprising: a first optical mechanism and a reproduction circuit for reproducing pits and/or spaces formed on the optical recording medium, wherein said first optical mechanism is further configured for irradiating a first recording pulse stream having two first recording pulses followed by an interval corresponding to a width of the first recording pulse and a second recording pulse stream having two first recording pulses followed by an interval having a length longer than the width of the first recording pulse; a strategy circuit for varying power of the first recording pulse based on said reproduced pits and/or spaces and for varying a width of the second recording pulse based on said reproduced pits and/or spaces; and a strategy determination circuit for comparing a signal obtained by reproducing the pits and/or spaces formed by irradiating the first recording pulse stream with a signal obtained by reproducing the pits and/or spaces formed by irradiating the second recording pulse stream and for determining whether or not a reproduction result is correct based on the comparison result.
