    • An optical card including a card substrate having a recess, and an optical recording member including, in the following order, a surface hard layer, a transparent protective layer, a pattern layer, and an optical recording material layer. The optical recording member is embedded in the recess through an adhesive layer so that the optical recording material layer is in contact with the adhesive layer. The end face of the optical recording member and the side face of the recess of the card substrate respectively have particular tapers facing each other. The optical recording member is embedded in the recess of the card substrate so that the end face of the optical recording member is not exposed from the card substrate.
    • 一种光卡,包括具有凹槽的卡片基板和光学记录元件,其按以下顺序包括表面硬质层,透明保护层,图案层和光学记录材料层。 光学记录部件通过粘合剂层嵌入凹部中,使得光学记录材料层与粘合剂层接触。 光记录部件的端面和卡片基板的凹部的侧面分别具有彼此面对的特定锥形。 光记录部件嵌入在卡片基板的凹部中,使得光记录部件的端面不会从卡片基板露出。
