Patent ID: 6975571

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 predetermined by a combination table of a preceding space length and a mark length and a back-end pulse edge position predetermined by a combination table of a mark length and a following space length, a random pattern signal is recorded (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 higher than a fixed value (c), when the value of the jitter or the bit error rate is judged to be higher than the fixed value, first test pattern signals are recorded (d), edge intervals of the first test pattern signals after being reproduced are measured (e), and based on results obtained by measuring the edge intervals, optimum values of the front-end pulse edge position and the back-end pulse edge position are determined (f).
