Triangular-Shaped Main Pole Design With Natural Leading Edge Tapering For Maximizing The Aerial Density Capacity In Perpendicular Magnetic Recording

A write head comprising:

• a main pole (MP) configured to apply a magnetic flux to write media bits to a recording medium, wherein the MP is triangular in shape;
• a trailing shield configured to collect back the magnetic flux;
• a side shield (SS), a leading shield (LS), and a write shield (WS);
• a leading edge taper on the LS to create a taper angle on the MP to concentrate the magnetic flux in the MP;
• a side gap (SG) between the MP and the SS;
• a leading gap (LG) between the MP and the LS, wherein the MP is shifted away from the LG to provide an additional LG portion on a leading side of the MP, and wherein the taper angle is greater at the additional LG portion than at the LG;
• and
• a coil wrapping around the MP through a magnetic PP3 shield that is configured to direct a write current to saturate MP magnetization.
