Abstract

所述光盘的主要特征是光盘上用来同激光头相贴近的表面设有一个以金属薄膜为孔底的盲孔,且盲孔中充填了将金属薄膜覆盖的导电层,使用时首先使金属薄膜带上静电,然后放进驱动器,此时,驱动器内空气中的尘埃将沉积在光盘上,即使激光头上已积聚了尘埃,也会被吸附到光盘上,拿出光盘,消除静电,光盘上的尘埃很容易被清除,由此可见,本实用新型的光盘兼具了激光头的清洁功能。

Description

光盘
本实用新型涉及一种光盘。
光盘是记录信息的载体，它由存有信息符号的金属薄膜和将金属薄膜复盖的塑料壳体组成，该塑料壳体的上、下表面至金属薄膜的距离是不同的，其中距离小的下表面是同驱动器中的激光头相贴近的表面。将光盘放进驱动器，由激光头读取信息数据再输出，但激光头在使用中积聚了空气中的过多的尘埃后将影响激光头的读取质量。
本实用新型的目的是提供一种兼具激光头清洁功能的光盘。
本实用新型的解决方案是光盘上用来同激光头相贴近的表面设有一个以金属薄膜为孔底的盲孔，且该盲孔中充填了将金属薄膜复盖的导电层。
将上述导电层接到静电发生器上，使金属薄膜带上静电，而后将此带静电的光盘放进驱动器，此时，不论驱动器工作或不工作，空气中的尘埃将沉积在光盘上，而不会沉积在激光头上，既使激光头上已积聚了尘埃，也会被吸附到光盘上。拿出光盘，消除静电，光盘上的尘埃就很容易被清除，由此可见，本实用新型的解决方案使光盘又具有了清洁激光头的作用。
下面结合附图和实施例来阐明本实用新型的具体内容。
附图是本实用新型的结构图。
如图所示，所述光盘由存有信息符号的金属薄膜1和将该金属薄膜复盖的塑料壳体2组成，且塑料壳体2上用来同激光头相贴近的表面5设有以金属薄膜1为孔底的盲孔3，该盲孔3中充填了将金属薄膜1复盖的导电层4。本实施例的导电层4采用石墨，其用途是作为同静电发生器连接的接线极，同时也起到保护金属薄膜的作用。所述的盲孔3在注塑形成塑料壳体2的过程中同塑料壳体2一起形成。
