PERPENDICULAR MAGNETIC WRITE HEAD HAVING A TRAILING WRAP-AROUND MAGNETIC SHIELD MAGNETICALLY BIASED IN A CROSS TRACK DIRECTION
摘要:
A perpendicular magnetic write head having improved Bit Error Rate (BER), Adjacent Track Interference (ATI) and Far Track Interference (FTI). The write head includes a write pole and a trailing wrap-around magnetic shield. A permanent magnetic is located at either outer side of the shield. These magnets are magnetized to have magnetizations that are oriented in the same direction, in a direction that is perpendicular to the track direction and parallel with the air bearing surface.
