Abstract

Claims (13)

1. A magnetic recording transducer comprising:

a magnetoresistive sensor having an left side, a right side opposite to the left side, a left junction angle at the left side, a right junction angle at the right side, and a track width, the right junction angle and the left junction angle being characterized by a junction angle difference, the junction angle difference being not more than six degrees, the track width being less than one hundred nanometers;

a left hard bias structure residing adjacent to the left side of the magnetoresistive sensor; and

a right hard bias structure residing adjacent to the right side of the magnetoresistive sensor.

2. The magnetic recording transducer of claim 1 wherein the junction angle difference is not more than four degrees.

3. The magnetic recording transducer of claim 1 wherein the junction angle difference is not more than three degrees.

4. The magnetic recording transducer of claim 1 wherein the junction angle difference is not more than two degrees.

5. A disk drive comprising:

a slider;

a magnetic recording head coupled to the slider, the magnetic recording head including a magnetic recording transducer having a magnetoresistive sensor, the magnetoresistive sensor having a left side, a right side opposite to the left side, a left junction angle at the left side, a right junction angle at the right side, and a track width, the left junction angle and the right junction angle being characterized by a junction angle difference, the junction angle difference being not more than six degrees, the track width being less than one hundred nanometers.

6. The disk drive of claim 5 wherein the junction angle difference is not more than four degrees.

7. The disk drive of claim 5 wherein the junction angle difference is not more than three degrees.

8. The disk drive of claim 5 wherein the junction angle difference is not more than two degrees.
