    • An optical network system includes a first node that converts input signals of n systems into optical signals having wavelengths different for each of the systems and wavelength-multiplexes and transmits the optical signals and a second node that selects signals of n systems from the wavelength-multiplexed signals and outputs the signals. The first node includes an optical coupler that divides the input signals into operating system signals and redundant signals, TPNDs that convert the operating systems into optical signals, an optical switch that selects standby system signals from the redundant signals, and a TPND that converts the standby system signals into optical signals in a storage mode corresponding to a type of the standby system signals. The second node includes TPNDs that convert the optical signals converted from the operating system signals into signals of a type corresponding to the input signals, a TPND that converts the optical signals of the standby system signals into signals of the type of the input signals in a storage mode corresponding to the standby system signals, and an optical switch that selects an output destination of the signals output from the TPND.

    • This invention relates to a stamper for optical disc and a method for manufacturing an optical disc by using this stamper. A photoresist is applied to a substrate (2) and this photoresist is exposed, developed and then transferred to form a disc master which has a recess/protrusion pattern formed on its one side. The one side of the disc master (20) is etched to narrow the width of a protruding part constituting the recess/protrusion pattern, and the recess/protrusion pattern of the disc master (20) with the reduced width of the protruding part is transferred to form a stamper (30). The recess/protrusion pattern provided on the stamper (30) is transferred to form a predetermined pattern on a substrate of an optical disc.
    • 本发明涉及一种用于光盘的压模和使用该压模制造光盘的方法。 将光致抗蚀剂施加到基板(2)上,并将该光致抗蚀剂曝光,显影,然后转印以形成在其一侧上形成有凹凸图案的光盘母盘。 光盘主机(20)的一侧被蚀刻以使构成凹凸图案的突出部分的宽度变窄,并且传送具有减小的突出部分宽度的盘主机(20)的凹凸图案 以形成压模(30)。 设置在压模(30)上的凹凸图案被转印以在光盘的基板上形成预定图案。
