    摘要： Optical information active layer mainly composed of a quaternary system of Te-Ge-Sn-Au, with composition ratios of Te, Ge and Sn that lie within an area represented by points A B C D and E on FIG. 1, with an additional amount of Au that is 1-40 atomic % of the quaternary system of Te-Ge-Sn-Au. The optical information active layer can be melted readily by a laser diode thereby achieving a high recording sensitivity, because it contains Te.sub.2 Au alloy having low melting point, CHR and erasability after repeated use and long term storage are small, and since excessive Te in the information active layer is stabilized by formings of Ge Te Su Te and Au Te.

The apparatus includes a detector for detecting a leading edge of the pulse duration period and for producing a start signal thereupon, another detector for detecting a trailing edge of the pulse duration period and for producing a stop signal thereupon, a pattern setting circuit for setting a predetermined basic pattern, and a pattern generator for generating the basic pattern from its beginning in response to the start signal and for terminating the generation of the basic pattern in response to the stop signal. The apparatus further includes a circuit for forming a modulated signal using a full or portion of the basic pattern produced from the pattern generator. The laser output is produced in accordance with the modulated signal.

    摘要： A reversible optical information recording medium which permits recording, reproducing, erasing and rewriting at high speeds by means of laser beams. The reversible optical information recording medium has a recording thin film which is essentially constituted by Te-Au-O, and Ge or Se. In the system which employs Ge, the recording thin film is formed by addition of at least one selected from a group consisting of Sn, In, Bi and Sb, such as to reduce the Au content in the film composition. On the other hand, in the system which employs Se, a further improvement in the stability of the recorded signal is achievable by the addition of Ge, and an improvement in the recording/erasing sensitivities, particularly erasing sensitivity, can be enhanced by addition of at least one element selected from a group consisting of Sn, In, Bi and Sb. The recording/erasing mechanism in the reversible optical information recording medium of the invention mainly relies upon a change in the optical characteristic which in turn is caused mainly by a reversible phase change of Te. The phase change in the recording medium of the invention can be effected by a laser beam of an extremely low light power density and short irradiation time as compared with that required by the conventional optical information recording medium. This in turn permits much higher speed of recording and erasing of information over the conventional optical information recording medium.

    摘要： Disclosed is an optical information recording member which permits recording of optical information at a high speed and high density by means of energy of light or heat, as well as a high speed reproduction of the recorded information. The optical information recording member has a thin film formed on a substrate which thin film is made of TeOx constituted by a mixture of Te and TeO.sub.2 with a small amount of Au being added such that the contents of Te, O and Au in the thin film falls within a predetermined region limited in terms of atomic percent. The optical information recording member of the invention having the thin film of Te-O-Au system permits the information to be recorded in quite a short time thus allowing quite high speed of recording and reproduction as compared with the conventional recording film of TeOx system. The optical information recording member of the invention also brings about a higher recording sensitivity and a higher C/N ratio. Further, the optical information recording member may have a thermal diffusion layer of a metal having a higher heat conductivity than the thin film, formed on at least one side of the recording thin film, thereby making uniform and stabilizing the recording bits. In consequence, undesirable distortion of the recording bits is prevented even when an excessively large recording power is irradiated, thus affording a wider adaptability of the optical information recording member.
