Abstract

The disclosed technology includes a storage device including an interlaced magnetic recording (IMR) system, and a transducer head, including two writers, each writer including a write pole, wherein a width of a first write pole in a cross-track direction is substantially greater than a width of a second write pole in the cross-track direction, and wherein a down-track width of a front shield gap of the first write pole is substantially similar to down-track width of a front shield gap of the second write pole. In another implementation, the storage device includes an IMR system, and a transducer head, including two writers, each writer including a write pole, wherein a width of the first write pole in a cross-track direction is substantially greater than a width of a second write pole in a cross-track direction, and wherein a cross-track width of a side shield gap of the first write pole is substantially similar to a cross-track width of a side shield gap of the second write pole.
