Patent ID: 7088656

Claim:
A method for optically recording information in which recording and reproduction of information is performed in such a manner that a test recording is performed before recording an information signal on a rewritable optical information recording medium, wherein based on a front-end pulse edge position and a back-end pulse edge position that are predetermined, a random pattern signal according to predetermined recording power is recorded, a jitter or a bit error rate of the random pattern signal after being reproduced is measured, it is judged whether a value of the jitter or the bit error rate as a result of the measurement is not less than a fixed value, when the value of the jitter or the bit error rate is judged to be not less than the fixed value, first test pattern signals are recorded in such a manner that the recording power is set to a predetermined value, and based on results obtained by reproducing the first test pattern signals, optimum values of the front-end pulse edge position and the back-end pulse edge position are determined, and wherein based on the front-end pulse edge position and the back-end pulse edge position that are predetermined, a random pattern signal is recorded with predetermined recording power (a), a jitter or a bit error rate of the random pattern signal after being reproduced is measured (b), it is judged whether or not a value of the jitter or the bit error rate as a result of the measurement is not less than a fixed value (c), when the value of the jitter or the bit error rate is judged to be not less than the fixed value, second test pattern signals are recorded (d), and based on results obtained by reproducing the second test pattern signals, an optimum value of the recording power is determined (e).
