    • An optical disk recording medium includes a single layer disk substrate having a hub provided on one side which includes a circular magnetic plate for effecting chucking of the optical disk. On the opposite side of the disk substrate a reinforcing plate is attached for reducing disk warpage during chucking, loading etc. The circular magnetic plate includes a centering opening for disk chucking, while a center opening of the reinforcing plate is larger in diameter than the centering opening. The reinforcing plate covers a central opening formed in the disk substrate and includes a boss portion which is projected into the opening. A groove is provided in the reinforcing plate at the outer circumference of the boss portion for retaining excess adhesive when the substrate is affixed to the reinforcing plate.
    • 光盘记录介质包括单层盘基片,其具有一侧设置的毂,其包括用于实现光盘夹紧的圆形磁盘。 在盘基板的相对侧,安装有加强板,用于在夹紧,装载等期间减少盘翘曲。圆形磁板包括用于盘夹紧的定心开口,而加强板的中心开口的直径大于定心 开放 加强板覆盖形成在盘基板中的中心开口,并且包括突出到开口中的凸台部分。 在基板固定在加强板上时,在凸台部的外周侧的加强板上设置有用于保持多余的粘合剂的槽。
