Perpendicular magnetic recording write head with flux shaping layers on the write pole and magnetic recording system incorporating the write head

A magnetic recording disk drive perpendicular recording write head for magnetizing regions in data tracks of a magnetic recording layer on the disk, the head being formed on a slider having an air-bearing surface (ABS) for facing the recording layer and comprising:

• a substrate;
• a main pole on the substrate and having an end recessed from the ABS;
• a first flux shaping layer of magnetically permeable material on the main pole and having an end recessed from the ABS;
• a write pole on the first shaping layer and having an end substantially at the ABS;
• a second flux shaping layer of magnetically permeable material on the write pole and having an end recessed from the ABS;
• an electrically conductive coil wrapped around the main pole for generating magnetic flux in the main pole and its connected write pole;
• first and second return poles spaced on opposite sides of the write pole in the along-the-track direction;
• a leading shield having an end substantially at the ABS and located between the write pole end and the first return pole and spaced from the write pole end in the along-the-track direction;
• and
• a trailing shield having an end substantially at the ABS and located between the write pole end and the second return pole and spaced from the write pole end in the along-the-track direction.
