摘要

PURPOSE: An optical information recording method, an optical information recording device and an optical information recording medium are provided to enable a laser driving circuit to differentiate power levels of a front end pulse and a rear end pulse from a power level of a middle pulse, while a recording signal edge compensation circuit compensates for an edge position of a recording pulse. CONSTITUTION: A modulation circuit(3) generates a modulated signal(recording data signal)(11). A recording signal generation circuit(4) drives a laser according to the modulated signal(11), and generates a recording signal(12) to divide the recording signal(12) into a front end pulse signal, a middle pulse signal, and a rear end pulse signal. A recording signal edge compensation circuit(5) compensates for front end pulse edge and rear end pulse edge positions of the recording signal(12). A laser driving circuit(6) modulates a current for driving the laser within an optical head(7) according to the compensated recording signal(13), and determines a power level of the laser.
