Zusammenfassung:Aspects of the present disclosure generally relate to a magnetic recording head of a magnetic recording device that facilitates generating a downtrack magnetic bias field to enhance writing. During magnetic writing using the magnetic recording head, a bias current is directed in a cross-track direction on the trailing side of the main pole. Bias current flowing in the cross-track direction on a leading side of the main pole is reduced or eliminated. The bias current flowing in the cross-track direction on the trailing side of the main pole facilitates generating a magnetic field in a downtrack direction. The magnetic field in the downtrack direction is a bias field generated using the bias current. The magnetic bias field in the downtrack direction facilitates enhanced writing performance and increased areal density capability (ADC) for magnetic recording.
