Main pole layers in the two writers are separated by a cross-track width <10 microns to minimize read-write offset. Each of the driving coil (DC) and bucking coil (BC) have two outer portions forming a U shape with a front side, and each have a center portion connected to the front side proximate to an air bearing surface and a backend contacting an interconnect. A write current passes from a BC outer portion below the main pole in the selected writer through the BC center portion to the interconnect, and then through the DC center portion to a DC outer portion above the main pole in the selected writer. Area density capability mean and sigma are improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic core and coil design for double perpendicular magnetic recording (PMR) writers","description":"A dual perpendicular magnetic recording writer is disclosed wherein the better of two writers on a slider is determined by performance testing, and is then integrated into a head gimbal assembly.
