Claim Text:
1. A magnetic transducer having air-bearing surface (ABS) comprising: a main pole, a portion of the main pole residing at the ABS; at least one coil configured to energize the main pole; a side shield; and a side gap between the main pole and the side shield, the side gap being nonmagnetic, the side gap including a first side gap and a second side gap, the first side gap being conformal with the main pole, the second side gap being conformal with the main pole, the first side gap being between the second side gap and the ABS, the second side gap being wider than the first side gap, the first side gap having a first width, the second side gap has a second width at least twice the first width, the second width being not more than sixty nanometers greater than the first width; wherein the first side gap terminates not more than one hundred nanometers from the ABS.
