Method and system for providing a read transducer having an adaptive read sensor track width

A magnetic recording head having an air-bearing surface (ABS) comprising:

• a write transducer including a pole having a pole tip, a portion of the pole tip having a surface residing at the ABS and having a plurality of pole sidewalls extending from the ABS at a nose chisel angle from a stripe height direction, the nose chisel angle corresponding to an actual writer nose chisel angle;
• and
• a read transducer coupled with the write transducer and including a first shield, a second shield, and a read sensor between the first shield and the second shield, the read sensor having a plurality of sidewalls and extending along the stripe height direction perpendicular to the ABS, a first portion of the read sensor at the ABS having a first width in a track width direction parallel to the ABS, a second portion of the read sensor recessed from the ABS along the stripe height direction having a second width in the track width direction, the second width being greater than the first width, the plurality of sidewalls extending from the ABS at a read sensor angle from the stripe height direction, the read sensor angle is within ten degrees of the actual writer nose chisel angle.

A disk drive comprising:

• at least one disk;
• at least one slider including at least one magnetic read transducer having an air-bearing surface (ABS) and a write transducer having the ABS, the write transducer including a pole having a pole tip, a portion of the pole tip having a surface residing at the ABS and having a plurality of pole sidewalls extending from the ABS at a nose chisel angle from a stripe height direction, the nose chisel angle corresponding to an actual writer nose chisel angle, the read transducer coupled with the write transducer and including a first shield, a second shield, and a read sensor between the first shield and the second shield, the read sensor having a plurality of sidewalls and extending along the stripe height direction perpendicular to the ABS, a first portion of the read sensor at the ABS having a first width in a track width direction parallel to the ABS, a second portion of the read sensor recessed from the ABS along the stripe height direction having a second width in the track width direction, the second width being greater than the first width, the plurality of sidewalls extending from the ABS at a read sensor angle from the stripe height direction, the read sensor angle is within ten degrees of the actual writer nose chisel angle.
