摘要： By using an information recording medium comprising at least a substrate and an information recording film which is mounted on the above substrate and changes the physical property under irradiation of a recording energy beam, wherein the surface of the information recording area of the above substrate is uneven, both surfaces of the above recording film are also uneven, and an inorganic protective layer is provided in contact with the surface of the above recording film opposite to the above substrate, fine recording points can be formed stably without complicated control of the recording power and recording waveform so that an optical disk unit can record data simply in high density.

摘要： The present invention relates to a method of recording on a rewritable recording medium using a laser beam capable of producing at least three discreet levels of power. The three levels of power used for writing to the recording medium is greater than the power required for reading. The present method is unique in that the power level of the laser beam is modulated between high, intermediate, and low levels over a time period so that at least three discreet power levels are radiated to the recording medium during recording. The increment of the radiation energy of the upward pulse from the intermediate level toward the high level is within the range of 0.8 to 1.2 times the decrement of the radiation energy of the downward pulse from the intermediate level to the low level. The present invention provides high density recording capability with minimum non-erasure areas even when the recording medium is formed from a high velocity crystallization (high speed erasure).
摘要翻译：本发明涉及使用能够产生至少三个谨慎的功率的激光束在可重写记录介质上进行记录的方法。用于写入记录介质的三个电源电平大于读取所需的功率。本方法的独特之处在于，激光束的功率电平在一段时间内在高电平，中间电平和低电平之间被调制，使得在记录期间至少三个分立的功率电平被辐射到记录介质。上升脉冲从中间电平向高电平的辐射能量的增量在从中间电平到低电平的向下脉冲的辐射能量减少的0.8到1.2倍的范围内。即使当高速结晶（高速擦除）形成记录介质时，本发明提供具有最小非擦除区域的高密度记录能力。

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： 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.
