Abstract
An improved load beam/flexure assembly for mini Winchester disk drives is disclosed. The load beam is substantially straight where it is attached to the arm as opposed to the prior art 2.degree. 20' bend. Furthermore, the side flange edges of the load beam are tapered towards the slider end of the load beam and the side flanges have wire tube guiding tabs, allowing for the elimination of the split finger so that the slider arm end is substantially flat. The flexure is also designed to have the surface that is attached to the slider to be substantially parallel to the elongated load beam, instead of the prior art 2.degree. 20' angle of the prior art. Also, the load beam arm end is secured to the arm by ball staking with the arm end of the load beam positioned between the insert and the arm with the insert having a boss passing through the load beam. The result of these combinations is a reduction of the disk to disk spacing of approximately 50%, from 300 mils to about 160 mils.
