    • A magnetic head suspension having a thin metallic plate as a substrate which is caused to have a new function besides a function as a spring. The magnetic head suspension plural lines for connecting a magnetic head and a control circuit board to each other are formed over a thin metallic plate having a spring property through an insulating layer, and are integrated with the thin metallic plate A metallic pad made of a same metal layer as the plural lines is formed independently of the lines, an opening is made in a portion of the metallic pad to penetrate the insulating layer and then to reach the thin metallic plate, and an electroconductive region is formed into the opening by metal plating, thereby connecting the metallic pad and the thin metallic plate electrically to each other. Thereby, the desired portions of the suspension can be grounded through this simple structure without adopting a complicated structure wherein additional special lines for grounding are not separately laid besides the lines, which are lines for connecting a magnetic head and a control circuit board to each other.
    • 具有作为基板的薄金属板的磁头悬架,除了作为弹簧的功能之外还具有新的功能。 用于将磁头和控制电路板彼此连接的多个磁头悬挂在通过绝缘层具有弹性的薄金属板上形成,并且与金属板一体形成由其制成的金属垫 作为多条线的金属层独立于线形成,在金属垫的一部分上形成开口以穿透绝缘层,然后到达薄金属板,并且通过金属电镀形成导电区域到开口中 从而将金属垫和薄金属板彼此电连接。 因此,通过这种简单的结构,悬架的期望部分可以通过这种简单的结构接地,而不采用复杂的结构,其中除了用于将磁头和控制电路板彼此连接的线之外的线之外,不需要分开布置附加的接地专用线 。
