摘要： A method of recording information by changing a recording medium through irradiation with an energy beam such as a light beam, electron beam or the like. A single pulse or a plurality of pulses are employed for forming recorded dots. The pulse has a pulse width shorter than a time required for the center of energy beam spot to move from one to other end of the dot upon recording thereof. By virtue of the possibility of reversible change even in a recording film susceptible to high rate speed of change, the rate of information transfer can be increased. Over-write recording can also be accomplished with the single laser beam. An increased amount of information can be handled in the recording and reproduction.

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： An information recording method and apparatus therefor utilizes an information recording medium having a recording film enabling reversible phase change. The information recording medium is irradiated with an energy beam while relatively moving the information recording medium and the energy beam so as to at least enable recording of information in accordance with phase state changes of the recording film caused by irradiation of the energy beam. The energy beam is modulated so that an intensity of the energy beam obtains a first level having a high power for one portion of coded data information to be recorded, obtains a second level different from the first level for a predetermined time for another portion of the coded data information, and then again obtains the first level to enable recording of the coded data information independently of a previous recording state on the information recording medium.

摘要： A separation type optical head according to the present invention includes at least a light source portion for emitting collimated beams, a focusing device (a focusing lens) for focusing the collimated beams onto an information recording surface of an optical disc medium, a focal point control mechanism for the position of the spot on the information recording surface, and a photo-detection portion for receiving beams reflected by the information recording surface. The structure is divided into a fixed portion including the light source portion and the photo-detection portion and a movable portion including the focusing device (focusing lens) and the focal point control mechanism. At least the movable portion of the separation type optical head is movably accommodated n a frame (sealing case) for the optical head so as to prevent irregular vibrations of the movable portion due to high speed air flows or turbulence. Furthermore, a focal point control mechanism of an air float type may be employed in the movable portion of the separation type optical head so as to actively utilize the high speed air flow generated due to the rotation of the disc medium to perform a rough adjustment of the focal point of the focusing device.

摘要： A method for separating and enriching isotopes in an efficient and low-cost manner from a condensation-system (liquid or/and solid) material including two or more different isotopes by taking advantage of the sedimentation of atoms through an acceleration field by ultra-high speed rotation. The condensation-system material is placed in a sedimentation tank which is then housed in a supercentrifuge. The supercentrifuge in its rotor is rotation driven by an ultra-high speed rotation power source, and an acceleration field of energy of 100000 G to 1500000 G, i.e., about 100 to 800 m/s in terms of peripheral velocity, is applied to the above condensed (liquid or/and solid) material under such a temperature that is specified by an isotope material to be enriched. In this case, a difference in centrifugal force applied is provided between the isotopes in the condensed (liquid or/and solid) material comprising the at least two isotopes. By virtue of sedimentation by taking advantage of this difference, isotope atoms within the condensed material interact, and, consequently, separation and enrichment of the isotopes can be realized in a higher efficiency than the case where gas is used, by conducting the separation and enrichment of the isotopes within the liquid material, using an effective material, and using a multistaged rotor system.
