摘要： Recording information is disclosed in which an information recording medium is irradiated with a recording energy beam that is power-modulated into at least a record power level and a record-ready power level lower than the record power level. The information is recorded on the recording medium in the form of length and interval of a mark portion. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion.

摘要： An information recording medium capable of high-density recording and accurate reproduction and also capable of repeated recording and reproduction, an information recording device that employs the information recording medium has a Co—Si oxide thin film 1 constructed such that columnar crystals 2 are separated by an intergranular phase 3 which contains SiO2 having a lower coefficient of thermal conductivity than the columnar crystals 2. Therefore, the intergranular phase 3 prevents heat transfer from one columnar crystal 2 to another. In addition, the intergranular phase 3 separates columnar crystals 2 from each other, so that the crystalline structure of each columnar crystal 2 is not affected by its adjacent columnar crystal 2. The advantage of such construction is that the columnar crystals 2 do not undergo phase transformation except for those which were given energy necessary for phase transformation directly from the laser beam, and hence columnar crystals 2 overheated by the laser beam do not affect their adjacent columnar crystals. Thus it is possible to accurately form recording pits whose mark length is smaller than the laser beam diameter.

摘要： A method for recording information is disclosed in which an information recording medium is irradiated with a recording energy beam power-modulated into at least a record power level and a record-ready power level lower than the record power level. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion. Also, only in the case where the energy beam is modulated by the power lower in power level than the record-ready power level after the last pulse of the energy beam pulse train including at least one pulse for forming a mark portion and the mark portion is followed by a space portion of a predetermined length, the particular radiation energy of low power level is reduced as compared with when the mark portion is followed by a space potion of a different length. The radiation energy is increased and/or decreased.

摘要： A multilayered optical disk having n recording layers is designed in such a manner that the transmittance Ti of the ith layer from a light-incident side satisfies the relationship: ∏ i - l j - i ⁢ T i 2 ≥ n - j + l n when the light is focused on a recording film of the jth layer. By doing so, the recording/reading property of a multilayered medium is improved.

摘要： An optical reproduction apparatus for reproducing information from an optical recording medium having grooves and lands alternately provided in a radial direction, information recording areas being formed in both of said grooves and said lands, and at least one prepit region where a groove is not formed. In the prepit region, first information marks are disposed on a virtual extension of a first boundary between one groove and one adjacent land and second information marks are disposed on a virtual extension of a second boundary between the one groove and an other adjacent land. A trailing edge of the first information marks is aligned in the radial direction. The optical reproduction apparatus includes an irradiation source for irradiating a light spot on the optical recording medium, a detector for detecting a reflected light from the optical recording medium, and a reproducer for reproducing information by using a signal from the detector.

摘要： The optical recording medium has sandwiched between protective layers a mask layer whose refractive index is changed in one part within a light spot when irradiated with a laser beam of 2 to 4 mW. In a region where the refractive index is changed or in other remaining regions, the difference in the amount of reflected light between the crystalline state and the amorphous state is so small that a reproduced signal is difficult to identify. By reducing the size of a portion where the reproduced signal can be seen, it is possible to read high-density recorded information.
