Abstract

This article describes a technique for fastening a magnetic head suspension to an access arm in which precision rivets are utilized as both an accurate aligning device as well as the fastener. The suspension 1 is provided with two accurately located mounting slots 2 and 3, and the access arm 4 is preassembled with two rivets 5 with clearance under the rivet heads 6. The suspension 1 is accurately positioned by engaging the slots 2 and 3 with the rivet shanks. As shown in the lower figure, slot 2 has a configuration in which the end walls of the slot comprise angular end surfaces 7, and slot 3 has a configuration in which the end 8 of the slot is substantially square. The suspension is accurately positioned both longitudinally and laterally by three location surfaces.

Self-Aligning Suspension to Arm Attachment by Rivets

This article describes a technique for fastening a magnetic head suspension to an access arm in which precision rivets are utilized as both an accurate aligning device as well as the fastener. The suspension 1 is provided with two accurately located mounting slots 2 and 3, and the access arm 4 is preassembled with two rivets 5 with clearance under the rivet heads 6. The suspension 1 is accurately positioned by engaging the slots 2 and 3 with the rivet shanks. As shown in the lower figure, slot 2 has a configuration in which the end walls of the slot comprise angular end surfaces 7, and slot 3 has a configuration in which the end 8 of the slot is substantially square. The suspension is accurately positioned both longitudinally and laterally by three location surfaces. The location surfaces comprise the angular ends 7 of slot 2 and the square end 8 of slot 3. While the suspension is held in a position accurately aligned to the location surfaces, the rivets 5 are driven to fix the suspension 1 in an accurately aligned position on the access arm 4.
