    • An optical information recording medium 10, being a reloadable optical information recording medium, has a first surface on which a pre-group is formed. A lower protective multi-layer film 2 consisting of a total of four film layers, a recording film layer 3, an upper protective film layer 4 and a reflective film layer 5 are successively accumulated on the first surface. On a second surface opposed to the first surface, there is formed an anti-reflective multi-layer film 6 consisting of an anti-reflective film (I) layer 6a and an anti-reflective film (II) layer 6b. Provided with the anti-reflective multi-layer film 6, the optical information recording medium 10 can eliminate reflections of irradiated light on the surface of its substrate. According to such an optical information recording medium, when either of the recorded region and the erased region of the recording film layer has a lower reflectance, the value of that reflectance can be further reduced without reducing the value of a reflectance of the other of the recorded region and the erased region. Accordingly, the amplitude modulation factor of the optical information recording medium can be increased with improvement of the C/N ratio and a reduction of reading errors.
    • 作为可重新加载的光学信息记录介质的光学信息记录介质10具有形成预组的第一表面。 在第一表面上依次累积由总共四个薄膜层构成的下保护性多层膜2,记录膜层3,上保护膜层4和反射膜层5。 在与第一表面相对的第二表面上形成由抗反射膜(I)层6a和抗反射膜(II)层6b组成的抗反射多层膜6。 设置有抗反射多层膜6,光信息记录介质10可以消除照射光在其基板表面上的反射。 根据这样的光学信息记录介质,当记录膜层的记录区域和擦除区域中的任一个具有较低的反射率时,可以进一步降低该反射率的值,而不会降低另一个的反射率值 记录区域和擦除区域。 因此,可以随着C / N比的提高和读取误差的减小而增加光信息记录介质的幅度调制系数。

    • In a rewritable optical information recording medium, a transparent interference layer, a translucent interference layer, a lower protection layer, a recording layer, an upper protection layer, and a reflection layer are formed on a substrate in that order. The transparent interference layer has a reflectance which changes in accordance with a wavelength of a beam incident on the substrate, and the translucent interference layer has a light transmittance smaller than that of the transparent interference layer. In this constitution, by determining appropriate thicknesses of the above-mentioned layers, a reflectance of a non-recorded portion of the recording medium with respect to a reproducing beam can be increased. Further, reflectances of the non-recorded and recorded portions with respect to a recording and erasing beam can be decreased, so that it becomes easy to record and erase information in the recording medium.
    • 在可重写光信息记录介质中,依次在基板上形成透明干涉层,半透明干涉层,下保护层,记录层,上保护层和反射层。 透明干涉层的反射率根据入射到基板上的光束的波长而变化,透光性干涉层的透光率比透明干涉层的透光率小。 在这种结构中,通过确定上述层的适当厚度,可以增加记录介质的非记录部分相对于再现光束的反射率。 此外,可以减少相对于记录和擦除光束的未记录和记录的部分的反射,使得易于在记录介质中记录和擦除信息。

    • An electronic apparatus includes: a display screen; a power supply switch; a memory for storing a plurality patterns of graphic data, select information indicating which graphic data is selected, and the number of times by which the power supply switch is operated; a controller responsive to the power supply switch being operated for controlling the display screen to display graphic data of a pattern specified by the select information; and a device for updating in accordance with a predetermined scheme the select information and the number of times of operation of the power supply switch, if the power supply switch is operated and the number of times of operation of the power supply switch satisfies predetermined conditions. For example, when the power supply switch is operated a predetermined times, a dialog screen for selecting the next pattern is displayed. The patterns may be divided into groups so that upon operating the power supply switch predetermined times, the next pattern of the group is selected, and ultimately the dialog for selecting the next group is displayed.
