ABSTRACT:
A magnetic head supporting mechanism for positioning a magnetic head at a target track on the surface of a magnetic disk includes an arm section for moving the magnetic head to radially access different data tracks of the disk. A suspension element includes a mount section securing the suspension element to the arm section and a resilient section integral with the mount section and a rigid load beam section integral with that resilient section. A magnetic head slider assembly is supported at the free end of the load beam section opposing the surface of the magnetic disk. A flexible resin mass is firmly attached to the surface of the resilient section with the surface of the flexible resin being free except for that portion which effects attachment of the flexible resin to the suspension element. The resin may be one from the group consisting of two-pack epoxy adhesive, a one-pack thermosetting adhesive and an ultraviolet curing adhesive. Preferably the elongation of the flexible resin is between 50 and 70 percent, and the flexible resin is preferably of convex shape with the convex resin of a height of about 0.3 mm.
