Abstract

A base layer for a suspension. The base layer includes a structure. The structure has a slider end portion and a tail portion. The structure includes an opening in the tail portion. The opening provides access to a conductive assembly coupleable there with. The structure also includes a strengthening member integrated within said opening.

Claims (26)

1. A suspension for a disk drive and comprising:

a structure layer having an end and an opposite end;

a layer coupled to said structure layer;

a conductor layer interposed between said structure layer and said layer;

an opening in said structure layer, said opening disposed within said opposite end, said opening access to said conductor layer; and

a strengthening member disposed in said opening.

2. The suspension as recited in claim 1 further comprising:

a dielectric layer interposed between said structure layer and said conductor layer.

3. The suspension as recited in claim 1 wherein said opening further comprises:

two or more opening portions.

4. The suspension as recited in claim 3 wherein said strengthening member is integrated between each of said two or more opening portions.

5. The suspension as recited in claim 3 wherein said structure layer is fabricated of stainless steel.

6. A disk drive comprising:

a housing;

a disk pack mounted to the housing and having at least one disk that is/are rotatable relative to the housing, the disk pack defining an axis of rotation and a radial direction relative to the axis;

an actuator mounted to the housing and being movable relative to the disk pack, the actuator having one or more arms extending there from; and

an electrical lead suspension, said electrical lead suspension (ELS) having a read/write head coupled therewith; said ELS comprising:

a structure layer having an end and an opposite end;

a layer coupled to said structure layer;

a conductor layer interposed between said structure layer and said layer;

an opening in said structure layer, said opening disposed within said opposite end, said opening access to said conductor layer; and

a strengthening member disposed in said opening.

7. The disk drive as recited in claim 6 wherein said opening further comprises:

a plurality of opening portions, said plurality numbering more that two.

8. The disk drive as recited in claim 7 wherein said strengthening member is interwoven within said plurality of opening portions.

9. The disk drive as recited in claim 6 wherein said structure layer is stainless steel.
