ABSTRACT:
A magnetic head suspension assembly includes a load beam which enables a close disk-to-disk spacing in a disk drive, high production yield, and increased torsional stiffness and resistance to vibrational modes. The load beam has a low profile, high resonance configuration, which minimizes the overall size of the magnetic head suspension assembly, and which improves manufacturability and robustness of magnetic head suspension assemblies by increasing the load beam resonance frequency and reducing the oscillation gain. The load beam is formed with a forward section that extends rearwardly into a central major section, a flexure secured to the forward section, and an air bearing slider secured to the flexure for free gimbaling motion while flying above an associated disk during operation in a disk drive. The forward section of the load beam covers substantially the entire surface of said flexure to provide it with sufficient rigidity and support. The load beam further includes a rail that extends partly above and partly below the major section, such that the part that extends above the major section tapers progressively from one end to another. The rail defines a U-shaped or V-shaped trough.
