    • The structure of optical memory disk like optical/magnetic hard disk is used in compact disks, laser disks, computers. The structure forms a lower-mirror layer (32), a recording layer (33) and an upper-mirror layer (34) on a substrate (31) in order, makes transparent the upper/lower mirror layer in the wave length region of probe beam different from the wave length of recording beam, sets polarizing difference of recording beam and probe beam at about 45., maks the reflection ratio of upper mirror layer to be under 30% and sects the lower mirror layer to make total reflection and decide the thickness of recording layer by initial phase value where the polarization of recording beam is maximum.
    • 光存储盘如光/硬盘的结构用于光盘,激光盘,计算机。 该结构依次在基板(31)上形成下镜层(32),记录层(33)和上镜层(34),使得在上下镜面层 探头光束与记录光束的波长不同,将记录光束和探测光束的偏振差设置在约45°,将上镜层的反射率设置在30%以下,并将下镜面层进行全反射,并决定 通过记录光束的极化最大的初始相位值记录层的厚度。
