    • In accordance with the teachings of the present invention, an optical disc having a reduced planar thickness is provided. In accordance with a particular embodiment of the present invention, the optical disc includes a central clamping area that defines a central aperture operable to be engaged by a spindle mechanism of an optical disc drive, an optically-readable data storage area substantially surrounding the central clamping area, the optically-readable data storage area having a planar thickness of less than 1.20 mm, and one or more stacker elements coupled to, or integral with, the central clamping area, the stacker elements configured to increase the thickness of the central clamping area above the planar thickness of the optically-readable data storage area. In particular embodiments, the optical disc may further include a magnetic stripe disposed upon one surface of the optical disc.
    • 根据本发明的教导,提供了具有减小的平面厚度的光盘。 根据本发明的特定实施例,光盘包括中心夹持区域,其限定可操作地由光盘驱动器的主轴机构接合的中心孔,基本上围绕中心夹持的光学可读数据存储区域 所述光学可读数据存储区具有小于1.20mm的平面厚度,以及一个或多个与所述中心夹持区域耦合或与所述中心夹紧区域成一体的堆叠器元件,所述堆叠器元件被配置为增加所述中心夹持区域的厚度 高于光学可读数据存储区域的平面厚度。 在特定实施例中,光盘还可以包括设置在光盘的一个表面上的磁条。
