Claims
- 1. A bottleneck magnetoresistive sensor element having a central wide portion with opposed substantially parallel sides and two ends, a narrowing transition portion connected to each end with at least one inclined side, and a bottleneck portion connected to each transition portion, the bottleneck portion having a width less than the central wide portion and being rectangular in shape with the sides of the rectangle's long dimension being substantially parallel with the sides of said central region.
- 2. The magnetoresistive element of claim 1 wherein the shape is symmetrical about a centerline substantially parallel with the ends of said central wide portion.
- 3. The magnetoresistive element of claim 1 wherein the easy axis of the element is oriented in a direction parallel to the opposed parallel sides of the central wide portion.
- 4. The magnetoresistive element of claim 1 wherein the easy axis of the element is oriented in a direction skewed relative to the opposed parallel sides of the central wide portion.
