Abstract
A preloaded head arm assembly comprises a lightweight, low inertia frustoconical arm support to which a magnetic head is mounted at one end. The other end of the head arm support is coupled to an end of a rotatable shaft, on which the arm support can be pivoted. An electrical coil which is disposed within a magnetic field supplied by permanent magnet means is fastened to the other end of the shaft. The pivotable magnetic head arm assembly may be vertically adjusted to control flying height and angularly adjusted relative to the surface of a magnetic disk to correct for azimuth variations.
