<p>A disc drive arrangement including RW head actuator driven by an improved voice coil motor, having housing (31) (or other flux-return structure) which is fabricated and processed of "magnetic ductile iron" and so adapted to exhibit improved magnetic characteristics and operation (increased working flux and an increase in efficiency and effective power/acceleration for given current -- e.g., thus decreasing "access time") and is more readily machined than cast steel or like conventional metals.</p> |
