This article describes an improved method for attaching the gimbal spring to the swing arm for a recording head in a floppy disk drive. In conventional methods, the spring has been attached by three rivets, causing a gripping action of the gimbal spring resulting in torquing and distortion of the spring. In this improved method, the gimbal spring is hooked at the front of the arm and riveted only at the back of the spring (Fig. 1). As shown in Fig. 2, gimbal spring 10 is fastened at the back of the spring to swing arm 12 by rivets 16. The front end of the gimbal spring is loosely held at the front of arm 12 by plastic hook 14. The recess, within which the spring hooks, is wider than the thickness of the spring. This allows the spring to "float" and not be restrained by the hook.
