摘要： A method for recording information on an optical information recording medium 1, 11 having a plurality of recording layers for recording, reproducing or erasing data by irradiating a laser beam from one side, includes a temporary pulse condition determination step (S502), a test area reflected light measurement step (S502), a final pulse condition determination step (S503-S506) and a recording execution step (S506). The temporary pulse condition determination step includes performing test recordings on a test recording layer that is at least one recording layer among a plurality of recording layers and determining a temporary pulse condition including a laser beam intensity. The test area reflected light measurement step includes measuring a test area reflected light level that is a reflected light level of the laser beam in an area for the test recording. The final pulse condition determination step includes correcting the temporary pulse condition in accordance with the measured test area reflected light level so as to determine a final pulse condition. The recording execution step includes recording data with the final pulse condition.

摘要： An optical information recording medium includes a plurality of recording layers, a reflectance of at least one of the plurality of the recording layers in a non-initialized state with respect to a light beam for initialization being smaller than a reflectance of the same in an initialized state with respect to the light beam for initialization. The recording layers are initialized by irradiating, among the plurality of recording layers, the recording layer positioned farther from a light beam irradiation side with the light beam prior to irradiating the recording layer positioned closer to the light beam irradiation side, so that the initialized recording layers have no initialization irregularities. In initialization, at a position at a same distance in a radial direction on the optical information recording medium, the recording layer positioned farther from a light beam irradiation side is irradiated with one light beam before the recording layer positioned closer to the light beam irradiation side is irradiated with another light beam so that the plurality of recording layers are initialized at the same time by a light beam projecting operation in which the light beams are focused at different positions. This ensures the initialization without irregularities within a short time.

摘要： A plurality of optical heads each of which comprises an independent light source and optical system are provided on the same side with respect to a recording medium having a plurality of recording layers. Alternatively, with respect to at least one light source in an optical head having a single objective lens and a plurality of light sources, an optical path correction system is provided on an optical path unique to the light source, and while light emitted from one light source is focused on a specific recording layer by shifting of the objective lens, light irradiated from another light source is focused on another recording layer by the optical path correction system. Thus, information can be reproduced from or recorded in a plurality of recording layers simultaneously and an error in focusing of light onto the plurality of recording layers can be suppressed.
