摘要： PURPOSE:To blacken uniformly a recording layer in a short time and to prevent the damage of a resinous substrate by providing an electrically conductive transparent film between the recording layer and the resinous substrate and on the upper surface side of the recording layer. CONSTITUTION:A transparent film 7 consisting of indium and tin oxide is vapor- deposited on the surface of a resinous substrate 6 on which a light-guiding groove 5 is formed, an optical recording film 3 is formed thereon, and then a transparent film 7' identical to the above-mentioned film is vapor-deposited. Then the substrate is bonded to a resinous substrate 6' with an adhesive 4 to form a disk. When the recording medium is placed in a high-frequency magnetic field, the whole optical recording film can be heated by an eddy current generated in the films 7 and 7'. The blackening to transform from the amorphous to the crystalline state can be uniformly carried out in an extremely short time, and the damage of the resinous substrate can be prevented.

摘要： PURPOSE:To prevent separation even in a high-temperature, high-humidity atmosphere, to minimize the deterioration of a recording film, and improve the reliability by irradiating the entire groove formation surface of a disk base material in which a groove for light guidance is formed with far ultraviolet rays and providing cleaning effect. CONSTITUTION:The groove 2 for light guidance is formed in the disk base 1 made of polycarbonate resin, and the entire groove formation surface is irradiated with far ultraviolet rays 6. The ultraviolet-ray excited physically and chemically active layer 7 which is irradiated as mentioned above has effect for removing thin-film type stains and even an uneven surface layer deterioration layer, thereby obtaining an optically uniform base material surface. A recording film 3 is formed on the active layer 7 by vapor deposition or sputtering in a short time while the active layer 7 is held clean, and the entire external surface of the disk substrate 8 is covered with a protective film 4 made of ultraviolet- ray setting resin. Consequently, the surface of the base material is irradiated with far ultraviolet rays to increase greatly the adhesive strength of the recording film to the base material.

摘要： PURPOSE:To always keep the time length of a signal bit constant and to contrive a high density recording by adjusting the laser beam intensity at the time of forming the signal bit in accordance with the time length between the signal bits. CONSTITUTION:An information signal (b) corresponding to the time length between the signal bits is synchronized with its original signal (a) and simultaneously supplied to a laser beam intensity setting circuit 3 by a signal bit to bit time length detecting circuit 2. The laser beam intensity is previously set up in accordance with the number of pulses in a clock signal for the time length between the signal bits, so that the laser beam intensity is turned to be optimum for forming the signal bit by the laser beam intensity setting circuit 3. As a result, since the signal bit formed on an optical information recording medium 8 is always constant, a stable reproducing signal can be obtained. In addition, since the distance between the signal bits can be shortened, the recording density can hence be promoted.

摘要： PURPOSE:To enable the execution of recording and erasing with high quality and high reliability by the use of an inexpensive device by executing the recording by an AC signal and executing the erasing by the DC control using the same beam as the beam used for the recording. CONSTITUTION:The recording power subjected to AC modulation by the circular beam formed by using a semiconductor laser is projected on a previously crystallized recording film 5 to form amorphous bits 6, by which the recording is executed. The erasing is executed by recrystallizing the amorphous bits 6 by using the same circular beam as the beam used for the recording. The recording film is once melted when said film is heated and irradiated like DC by the erasing beam to the m.p. of the recording film 5 or above but the projection light is continuous like DC and, therefore, the heat is easily confined and the recording film is slowly cooled, by which the film is crystallized. The AC-modulated beam light is projected on the film and therefore, the film is melted discontinuously and the once melted parts are rapidly cooled to form the amorphous parts in the case of the recording. Both the recording and erasing are thus executed by only the circular beam formed by using a piece of the semiconductor laser and the erasing rate is improved as well.

The thickness of the dielectric layer 2a on the side where laser light 7 enters the recording layer 3, designated as Alambda/64n', is selected as A>12 where the wavelength of the laser light is designated as lambda and the refractive index of the dielectric layer as n'. The thickness of the dielectric layer 2b between the recording 3 and the reflection layer 4, designated as Blambda/64n', is selected at 3

摘要： PURPOSE:To obtain a sputtering device capable of control for required composition by providing both a means for detecting the rate of formation of a thin film and such a means that this detection value is compared with previously preset reference value and also sputtering conditions are subjected to feedback control based on the compared result. CONSTITUTION:A sputtering device main body 1 is provided with electrodes 3, 4 in the inside of a chamber 2 and both a base plate 5 for forming a thin film and a target 6 are fitted thereon respectively. Fixed amount of sputtering gas 8 is introduced into the chamber 2 through a flow rate controller 7 for gas and the inside of the chamber 2 is kept at constant degree of vacuum. A high-frequency oscillator 10 is connected between the electrodes 3, 4 and high frequency is impressed to generate plasma 11 on the target 6 and a thin film is formed on the base plate. On the other hand, the rate of formation of the thin film is monitored with a detector 13 thereof using, i.e., a crystal resonator 12. This detection value is sent to an amplifier 14 and thereafter fed to a comparator 15 which compares it with reference value corresponding to previously preset rate and the flow rate of sputtering gas is subjected to feedback control with a controller 16 based on its output signal.

摘要： PURPOSE:To permit in-process control of the compsn. of a thin film to be formed so that the desired compsn. of the thin film is realized by controlling the conditions for forming the thin film in accordance with the in-process measurement of the thickness of the thin film formed and reflectivity spectra. CONSTITUTION:The Te atoms or molecules sputtered from a Te target 102 combine with O2 in a chamber 105 and form a thin TeOx film on a rotating substrate 108 at the time of forming; for example, the thin TeOx film by a sputtering method. The sputtering speed is controlled by a crystal resonator 110 method. A light projecting and receiving type optical fiber 114 is provided above the substrate 108 and light is projected through said fiber to the substrate 108. The reflected light thereof is guided to a spectrophotometric detector 116 where the light is spectrally separated. The separated rays of the light are detected as the spectra by the detecting element. The measurement signal obtd. in such a manner and the reference signal of the preset reflectivity spectra are compared and contrasted by a comparator 120 and the conditions for forming the thin film are so controlled as to minimize the difference therebetween.
