20130314882 | DYNAMIC LOOP WITH FOLD - A single layer dynamic loop is provided. A single layer dynamic loop includes a set of traces divided by a slit on the single layer dynamic loop, wherein the set of traces are divided into a first region and a second region; and wherein the single layer dynamic loop is folded along the slit to move at least part of the first region in relation to the second region. | 11-28-2013 |
20140285926 | COPPER RESIDUAL STRESS RELAXATION REDUCTION MEANS FOR HARD DISK DRIVE SLIDER GIMBALS - A hard drive gimbal trace circuit includes: a stainless steel gimbal strut (SGST) configured to support a transducer and nullify a natural pitch angle of a flexure from mechanical-coarse adjustment of the SGST; traces forming a trace structure, and being plastically deformed at a high strain region from the mechanical-coarse adjustment of the SGST; and a first protrusion and a second protrusion being at least partially disposed under the high strain region. The SGST has an edge which is disposed on the transducer side to be spaced apart from the traces in the high strain region and extends substantially parallel to the traces. The first protrusion and the second protrusion extend from the edge in an orthogonal direction to an extending direction of the traces and across the traces, and are disposed side by side in the extending direction of the traces. | 09-25-2014 |
20140293486 | CIRCUIT INTEGRATED SUSPENSION AND METHOD OF MANUFACTURE THEREOF - An Extended Circuit Integrated Suspension (ECIS) includes: a load beam, including a first plurality of traces disposed on a first side of the load beam and a first connection portion; and a flexure circuit which is disposed on an opposite side of the first side of the load beam and connected to the load beam by the first connection portion, and includes a second plurality of traces and a second connection portion to connect to the first plurality of traces on the load beam. | 10-02-2014 |
