Abstract:
A joint arrangement for connecting a drawbar to a carriage includes a push/pull device for the transmission of pushing and pulling forces arranged at the carriage end of the drawbar. The push/pull device comprises a mid-piece connected to the carriage side end of the drawbar, extending the drawbar in the longitudinal direction thereof which extends through an opening provided in the baseplate. A front spring plate and a rear spring plate are provided on the mid-piece with a front spring element between the front spring plate and the baseplate in the drawbar longitudinal direction and a corresponding rear spring element is provided between the baseplate and the rear spring plate. The front spring element and the rear spring element enclose the mid-piece of the push/pull device with a positive fit in order to guide and support the mid-piece of the push/pull device in the most effective manner possible within the baseplate and are themselves supported in the vertical direction on the baseplate and in particular on a recess region provided in the baseplate.

Abstract:
A magnetic recording device makes use of an “anchored” conductive stud which is securely attached within its surrounding insulator materials. The conductive stud is formed over a conductive layer which is coupled to or part of a read or a write head element of the magnetic recording device. The conductive stud has a top stud portion and a bottom undercut portion formed over the conductive layer. In one illustrated embodiment, the bottom undercut portion has a width that is greater than the width of the top stud portion. Since an insulator is formed around the conductive stud and over its bottom undercut portion, a secure coupling between the conductive stud and the conductive layer is provided. Preferably, the conductive layer is made of copper (Cu), the conductive stud is made of gold (Au), and the insulator is alumina (Al2O3). A seed layer may be formed between the conductive stud and the conductive layer. A method of making the conductive stud using a photolithography process is also disclosed.
