Abstract

A transducer head mounting assembly includes a stiff load beam with added formed tabs which closely approach the slider mounting groove sidewall, but do not interfere with the normal function of the slider, suspension and load beam. The tabs limit the ability of the mounting assembly to "wind up" when stiction occurs. The tabs quickly engage the suspension groove sidewalls to limit the rebound force that can cause damage to the head, disk or both. Fig. 1 shows a typical transducer carrying slider 4 with a mounting groove 5 (the nearer wall portion defining the mounting groove being broken away to expose the suspension 6). The load beam 7 (Fig. 2) is normally a stiff single-channel device. As shown, two added formed tabs 8 extend transversely and down from the principal channel portion of load beam 7. As illustrated in Fig.

Load Beam Antiwind-Up Structure

A transducer head mounting assembly includes a stiff load beam with added formed tabs which closely approach the slider mounting groove sidewall, but do not interfere with the normal function of the slider, suspension and load beam. The tabs limit the ability of the mounting assembly to "wind up" when stiction occurs. The tabs quickly engage the suspension groove sidewalls to limit the rebound force that can cause damage to the head, disk or both. Fig. 1 shows a typical transducer carrying slider 4 with a mounting groove 5 (the nearer wall portion defining the mounting groove being broken away to expose the suspension 6). The load beam 7 (Fig. 2) is normally a stiff single-channel device. As shown, two added formed tabs 8 extend transversely and down from the principal channel portion of load beam 7. As illustrated in Fig. 3, the clearance between the walls of groove 5 and load beam 7 is reduced from the "normal spacing" between the load beam channel portion and mounting groove sidewall to the "reduced spacing" between groove sidewall and added formed tabs 8. Thus, if the slider adheres to the disk surface, the assembly can only yield for the "reduced spacing" distance prior to positive engagement with the load beam, rather than the "normal spacing" previously present.
