Magnetic recording transducer
A magnetic recording transducer comprises a 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 right junction angle and the left junction angle are characterized by a junction angle difference of not more than six degrees. The track width is less than one hundred nanometers. The magnetic recording transducer further comprises 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.
