摘要： A plurality of types of recording pulse control rules for which the recording pulse waveform is determined according to the information signals to be recorded are stored in advance in an optical disk. When recording to the optical disk, information is recorded using a recording pulse where, due to the focused laser beam, the temperature in the recording layer cools more rapidly at a second information recording layer closer to the side where light is incident than at a first information recording layer farther away from the side where light is incident.

摘要： A recording and reproduction apparatus for a recording medium including a plurality of information layers includes a focusing signal generation section for generating focusing signals F+ and F− in accordance with a light beam reflected by the recording medium; a focusing control section for generating a focusing error signal in accordance with a difference between the focusing signals F+ and F−, and performing focusing control for maintaining a distance between a focal point of the light beam and a target information layer within a prescribed tolerable range; and a gain setting section for setting a focusing servo gain in accordance with the focusing error signal. The focusing signal generation section generates the focusing signals F+ F− so that values of components thereof based on the light beam reflected by an information layer other than the target information layer are substantially equal while focusing control is being performed.

摘要： An optical information recording medium includes a substrate 1 and two information layers (2, 4) formed on the substrate. The information layer is formed of a thin film showing a change that can be detected optically by irradiation of a light beam 7. A separating layer 3 that is transparent to a wavelength of the light beam 7 is formed between the information layers 2 and 4. Each information layer (2, 4) includes a sector area having sector address portions (9, 13) and data areas (8, 12) for recording information signals, the sector address portion and the data area being divided in the circumferential direction, and a management area (10, 14) for recording identification information about the amount of dislocation between the sector address portions 9 and 14 in the circumferential direction. Thus, the identification information about the amount of dislocation can be recorded, so that demodulation errors during reproduction can be reduced by switching amplification gain or slice level during reproduction according to the identification information. Also, stable data recording can be achieved by switching recording power according to a gate signal.
