摘要： PURPOSE:To obtain a reproduction signal improved in S/N by delaying the distance between a reproduction beam spot and another reproduction beam spot at a tail part by a time required for drive of a disk recording medium, then adding a photodetecting output. CONSTITUTION:The light beam supplied from a light source 1 is divided into two parts by half mirrors 13a and 13b and condensed on the same track T of a recording medium 4 in the form of beam spots 15a and 15b by objective lenses 14a and 14b. In such a case, the medium 4 is revolved at a fixed speed by a motor control circuit 8. Then the reflected light is transmitted again through lenses 14a and 14b and extracted by photoelectric transducers 16a and 16b in the form of reproduction signals. The output of the transducer 16a is sent to a delay element 17 and delayed there until the same information is delivered from the transducer 16b by the delay time control signal. A differential amplifier 12 amplifies differentially the reproduction signal sent from the transducer 16a with the time difference eliminated as well as the reproduction signal sent from the transducer 16b. Thus it is possible to obtain a reproduction signal having a satisfactory S/N.
摘要翻译：目的：为了通过将再现光束点与尾部的另一再现光束点之间的距离延迟驱动盘记录介质所需的时间来获得S / N改善的再现信号，然后添加光电检测输出。构成：从光源1供给的光束被半反射镜13a，13b分成两部分，并通过物镜14a，14b以光束点15a，15b的形式在记录媒体4的相同轨道T上聚光。在这种情况下，介质4通过电动机控制电路8以固定的速度旋转。然后，反射光再次通过透镜14a和14b传播，并以再现信号的形式由光电变换器16a和16b提取。换能器16a的输出被发送到延迟元件17并在那里被延迟，直到相同的信息通过延迟时间控制信号从换能器16b传送。差分放大器12差分地放大从消除的时间差以及从换能器16b发送的再生信号从换能器16a发送的再生信号。因此，可以获得令人满意的S / N的再现信号。

摘要： PURPOSE: To obtain optical information which is superior in waveform equivalent characteristic over a wide frequency range, by using focusing error information of a light beam which is illuminated to a recording medium, and controlling the waveform equivalent characteristic of a signal which is recorded and reproduced.
CONSTITUTION: A beam 2 for reproduction from a light source 1 reaches an optical disk 7 through an optical system 3, polarization beam splitter 4, and automatic focus control system 6. Its reflected light travels backward and is reflected by the polarization beam splitter 4 to be split into error detection light and reproduction light through an optical system 8. An error detection system 10 decides on the focusing state of the beam 2 for reproduction 2 and the automatic focus control system 6 is controlled by an automatic focus control signal 12. The reproduction light, on the other hand, is inputted as an information signal 15 to a variable transfer function circuit 14 through a regenrative amplifier 11 and its high frequency component is amplified relatively under the control of a focusing error signal 13 from the error detection system 10 to obtain a reproduced signal 16 which is superior in waveform equivalent characteristic over the wide frequency range.

摘要： PURPOSE:To enable high-speed selection by reducing mechanically movable parts, by arraying bright-spot scanning elements, utilizing ultrasonic surface elastic waves, in the radius direction of a disk. CONSTITUTION:Parallel laser light is guided as luminous flux into a waveguide through a prism coupler and deflected by being diffracted by an ultrasonic elastic wave excited by comb-tooth-shaped electrodes in the waveguide, thereby forming bright spots on a flank through a thin-film lens. The frequency of a high-frequency voltage applied to the comb-tooth-shaped electrodes is varied for bright-spot scanning. An array 38 of bright-spot scanning element having the said constitution (not shown in the figure) (See Patent Appl. No.1 Sho 55-12939) is arranged close to a magnetic disk 31 and a magnetic field generating element 33 is driven by a signal source 34 over irradiation with light, thereby recording a signal at a scanning position controlled by a controller 32.

摘要： PURPOSE:To keep the recording density on a recording medium at a constant level despite of a change of period in terms of time, i,e., evenin a transient state and regardless of the period of the driving signal voltage, by compensating the driving signal voltage in relation to its repeating period. CONSTITUTION:The recording is carried out by scanning a recording medium having the threshold value of recording density to the exposure value and by means of a light spot 1-25 which is modulated by a recording signal. When the width of the recording signal preceding the recorded signal in this recording is smaller than the prescribed value, the changing time point is shortened at the front edge of said recording signal. In such a way, the deterioration is previously compensated for the signal amplitude in case a reproduced light spot is finite and in a reproduction mode. Such a compensation is carried out by relating the driving signal voltage obtained when the light intensity is modulated to the recording wavelength.
