Patent ID: 7944647

Claim:
A data storage system comprising: a motor; an actuator arm operably coupled to the motor; a load beam attached to the actuator arm; a slider operably connected to the distal end of the load beam by a flexure, the slider comprising an air-bearing surface; a magnetic recording medium; and a transducing head mounted on a trailing face of the slider, and configured to read and write data to the magnetic recording medium, the transducing head comprising: a first pole and a second pole separated by a gap; a closure partially connecting the first pole and the second pole generally at the back of the first pole and the second pole, the closure including a first closure and a second closure split apart from each other; and a waveguide disposed in a distinct plane between the first and second poles and extending within the gap and between the first and second closures without bending, turning, or extending within the first pole or the second pole so as to decrease a magnetic reluctance and increase a write efficiency of the transducing head.
