Description

REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation of application Ser. No. 10 / 686,183, filed on Oct. 15, 2003, and entitled “Swaging-Optimized Baseplate For Disk Drive Head Suspension,” and which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION

[0002] The present invention relates generally to attachment structures such as baseplates for disk drive head suspensions. BACKGROUND OF THE INVENTION

[0003] Swage baseplates are widely used in disk drives to attach head suspensions to E-blocks, C-blocks or other actuator arms. Examples of these attachment structures and associated assembly methods are disclosed in the Wang et al. U.S. Patent Application Publication No. 2002 / 0145830, and the Hanrahan et al. U.S. Pat. Nos. 6,033,755 and 6,183,841, all of which are incorporated herein by reference.

[0004] Briefly, baseplates include a generally flat flange and a tubular boss tower extending from the flange. The flange is typically welded to a m...
