<p>An optical information processing method comprises a first step of supplying a driving current to a light source so as to emit a light beam, a second step of converging the light beam emitted from the light source and irradiating onto an optical recording medium, a third step of adjusting a focal point of the light beam on the medium, a fourth step of adjusting the driving current so that the power of the light beam is set to a predetermined value in a state in which the focal point is adjusted; a fifth step of storing the value of the driving current which is adjusted in the fourth step, and a sixth step of supplying the current of the value stored in the fifth step to the light source so as to emit the light beam and scanning on the medium by the light beam, and thereby recording, reproducing, or erasing information. Apparatus to embody the above method is also disclosed.</p> |
