Magnetic head supporting mechanism

A magnetic head supporting mechanism for positioning a magnetic head at a target track on the surface of a magnetic disk, comprising;

• an arm section for moving said magnetic head to radially access different data tracks of said magnetic disk;
• a suspension element made of a single resilient plate including, in order, a first section fixed to said arm section, a second section contiguous to said first section, and a third section contiguous to said second section;
• means coupled to said third section for rendering said third section rigid against bending forces, said suspension element being bent at said second section toward said magnetic disk;
• a magnetic head slider assembly supported at the free end of said third section opposing the surface of said magnetic disk;
• and
• a flexible resin firmly attached to the surface of said second section of said suspension element, with the surface of said flexible resin except for a portion of said flexible resin attaching to said suspension element, being open to the air.

• a suspension element made of a single resilient plate including, in order, a first section by which said suspension element is secured to said arm section, a second section integral with said first section, and a third section integral with said second section and provided with bent side edges forming integral flanges to respective sides of said third section;
• a magnetic head slider assembly supported at the free end of said third section opposing the surface of said magnetic disk;
• and
• a flexible resin firmly attached to the surface of said second section of said suspension element, with the surface of said flexible resin except for a portion of said flexible resin attaching to said suspension element, being open to the air, said flexible resin being any one selected from the group consisting of a two-pack epoxy adhesive, a one-pack thermosetting adhesive and an ultraviolet-curing adhesive.
