摘要： It is an object of the present invention to provide an optical recording disc which can record data constituted by a recording mark train including recording marks and blank regions neighboring recording marks therein and reproduce the data therefrom in a desired manner even in the case where the lengths of a recording mark and a blank region between neighboring recording marks are shorter than the resolution limit and whose storage capacity can be markedly increased.An optical recording disc is constituted so that data are recorded therein and data are reproduced therefrom with the irradiation with a laser beam and includes a laminated body formed by laminating a decomposition reaction layer 5 containing platinum oxide as a primary component and a light absorbing layer 7 so as to sandwich a second dielectric layer 6. The optical recording disc is further constituted so that when it is irradiated with the laser beam, a bubble pit is formed in the decomposition reaction layer 5 and fine particles of platinum precipitate into the bubble pit, thereby forming a recording mark in the decomposition reaction layer 5 and each of the fine particles of platinum has a particle diameter of 2 nm to 15 nm.

摘要： A method for setting recording power of recording light, capable of an appropriate setting for a multilayer optical recording medium. The recording power of the recording light for an information recording layer of the multilayer optical recording medium to be irradiated with, is set by: evaluating an information recording layer to be evaluated for recording power when all the information recording layer(s) lying closer to a light incident surface than the information recording layer to be evaluated does is/are in a low transmittance state; evaluating the information recording layer to be evaluated for recording power when all the information recording layer(s) lying closer to the light incident surface than the information recording layer to be evaluated does is/are in a high transmittance state; and determining ground information for setting recording power, based on these values of the recording power.

摘要： An optical disc has a data management area in a region on a radially inward side. Management information is recorded in the data management area as recording marks and spaces. The optical disc also has a data recording area on the outside of the data management area. Data to be read is recoded in the data recording area as recording marks and spaces. The information readout density of the data recording area is higher than that of the data management area. The read power of a readout laser beam during readout can be set smaller in the data management area than in the data recording area. In this manner, the read stability is significantly increased without reducing the information readout density.

摘要： A super resolution optical reproducing system, which can recognize a recording mark less than a resolution limit, removes the effect of a high-frequency noise component of a high power signal obtained by irradiating a laser beam with high read power. The same recording region of an optical recording medium is irradiated according to an irradiation spot by a laser beam with an ordinary read power and an irradiation spot by a laser beam with high read power to obtain a ordinary power signal and a high power signal. The ordinary power signal and the high power signal are normalized to an average level by high pass filters and low pass filters of a high power signal processing circuit and a ordinary power signal processing circuit. Then, a subtracter subtracts the ordinary power signal from the high power signal to obtain a substrated signal. The differential signal and a ordinary reproduced signal that has passed through a parallel processing circuit are amplitude-modulated by a pre-equalizer and a parallel pre-equalizer and then added up by an adder to form a composite signal. The composite signal is output as a reproduced signal.
