Abstract

The slider suspension configuration illustrated in Figs. 1 and 2 permits a motion normal to a media to be sensed by the transducer mounted in the slider, while restraining a motion lateral to the media. The suspension assembly includes a gimbal spring 1 supporting a slider-transducer assembly 2. Portions 3, 4, 5 and 6 are flat spring pivot sections of the rectangular gimbal spring 1. The remaining portions of the gimbal spring 1 are relatively rigid members. The slider 2 is fastened to a resilient support 7 for placement next to a media surface 8 (Fig. 2).

Rectilinear Motion Suspension for Magnetic Heads

The slider suspension configuration illustrated in Figs. 1 and 2 permits a motion normal to a media to be sensed by the transducer mounted in the slider, while restraining a motion lateral to the media. The suspension assembly includes a gimbal spring 1 supporting a slider-transducer assembly 2. Portions 3, 4, 5 and 6 are flat spring pivot sections of the rectangular gimbal spring 1. The remaining portions of the gimbal spring 1 are relatively rigid members. The slider 2 is fastened to a resilient support 7 for placement next to a media surface 8 (Fig.
2).

A bracket 9 mounts one end of the gimbal spring 1 to an arm assembly 10 used to position the suspension assembly laterally across the media surface 8 for the transducing operation. The second end of the gimbal spring 1 is restrained by a flat flexible strap 11 through a beam 12 which allows rotation and translation of a load beam 13 comprising beam 12 and support 7 connected to the gimbal spring 1, but does not allow a motion in a direction perpendicular to the media surface 8.

Fig. 3 shows a linkage system to illustrate the rectilinear motion obtained from the suspension assembly of Figs. 1 and 2. The rectilinear motion is obtained at point A, which corresponds to the slider 2. Link lengths AB=BC=BD. Points B and D are pinned joints, with D being pinned to a relatively solid surface. The pivot sections 3 and 5 are equivalent to the point B of Fig. 3. The pivot s...
