Scissor magnetic read head with wrap-around magnetic shield

A magnetic read head, comprising:

• a trailing magnetic shield;
• a leading magnetic shield;
• a sensor stack that includes first and second magnetic free layers that are anti-parallel coupled across a non-magnetic layer sandwiched there-between, the sensor stack having first and second laterally opposed sides sandwiched between the leading magnetic shield and the trailing magnetic shield;
• first and second magnetic side shield structures adjacent to and separated from each of the first and second sides of the sensor stack by a non-magnetic, electrically insulating layer, each of the first and second magnetic side shield structures including a first magnetic layer, a second magnetic layer and an exchange coupling layer sandwiched between the first and second magnetic layer and configured to anti-parallel couple the first and second magnetic layers;
• an exchange coupling layer sandwiched between the trailing magnetic shield and each of the first and second magnetic side shield structures and configured to anti-parallel couple the trailing magnetic shield with the second magnetic layer of the magnetic side shield structure;
• wherein the first magnetic layer is laterally aligned with the first magnetic free layer of the sensor stack and provides a magnetic bias field in a first direction parallel with an air bearing surface;
• and
• the second magnetic layer is laterally aligned with the second magnetic free layer of the sensor stack and provides a magnetic bias field in a second direction that is opposite to the first direction;
• and
• a layer of anti-ferromagnetic material, exchange coupled with the trailing magnetic shield so as to pin a magnetization of the trailing magnetic shield in a direction parallel with an air bearing surface of the sensor stack.

A magnetic data recording system, comprising:

• a housing;
• a magnetic media mounted within the housing;
• a slider;
• an actuator mounted within the housing for moving the slider adjacent to the magnetic media;
• a magnetic read sensor formed on the slider, the magnetic read sensor further comprising:
• a sensor stack that includes first and second magnetic free layers that are anti-parallel coupled across a non-magnetic layer sandwiched there-between;
• a magnetic side shield structure formed at a side of the sensor stack;
• and
• a non-magnetic, electrically insulating layer separating the magnetic side shield structure from the sensor stack;
• wherein:
• the magnetic side shield structure further comprises a first and second magnetic layers and an exchange coupling layer sandwiched between the first and second magnetic layers;
• the magnetic layers are anti-parallel coupled with one another across the exchange coupling layer;
• the first magnetic layer is laterally aligned with the first magnetic free layer of the sensor stack and provides a magnetic bias field in a first direction parallel with an air bearing surface;
• and
• the second magnetic layer is laterally aligned with the second magnetic free layer of the sensor stack and provides a magnetic bias field in a second direction that is opposite to the first direction.
