Magnetic write head having a coil adjacent to the main pole

A method for manufacturing a write coil in a magnetic write head, the method comprising:

• depositing a first insulation layer over exposed portions of a main pole and a stitch pole using atomic layer deposition;
• depositing a plating seed layer on said first insulation layer;
• applying a photolithographic process on said seed layer to enable plating of a coil portion on a portion of said seed layer;
• plating one or more copper coil portion on said portion of said seed layer immediately adjacent to said main pole but for said atomic layer deposited first insulation layer;
• and
• filling second insulation over said one or more coil portion.

A hard disk drive, comprising:

• a head slider comprising a magnetic write head;
• a magnetic-recording disk rotatably mounted on a spindle;
• a voice coil motor configured to move the head slider to access portions of the magnetic-recording disk;
• and
• wherein said write head comprises:
• a magnetic write pole extending to an air bearing surface;
• a magnetic return pole, magnetically connected with said write pole in a region removed from said air bearing surface;
• a write coil arranged around said write pole so as to induce a magnetic flux in said write pole when electrical current flows through said write coil, said write coil comprising:
• a plurality of lower coil portions positioned on a first side of said write pole;
• a plurality of upper coil portions positioned on a second side of said write pole opposing said first side;
• wherein said plurality of upper coil portions comprises at least one upper coil portion immediately adjacent to a main pole of said write pole but for only an atomic-layer-deposited insulation layer between said main pole and said at least one upper coil portion;
• and
• a plurality of electrically conductive tabs each connecting a lower coil portion with an upper coil portion.
