Tandem magnetic writer with independently addressable coils

A magnetic head,

• comprising:
• a pole;
• a first write gap in the pole;
• a first coil for generating a magnetic flux across the first write gap;
• a second write gap in the pole having at least a portion thereof aligned with the first write gap in a direction parallel to a direction of media travel thereover;
• and a second coil for generating a magnetic flux across the second write gap, the second coil being addressable independently of the first coil,
• wherein the first and second coils are formed on a common substrate,
• wherein the write gaps extend to opposite edges of the pole.

A system, comprising:

• a planar tape bearing surface;
• a first write gap positioned such that a magnetic flux emanates thereacross out of the tape bearing surface;
• a first coil for generating the magnetic flux across the first write gap, the first coil having portions of several turns aligned in a direction about parallel to a media facing surface;
• a second write gap positioned such that a magnetic flux emanates thereacross out of the tape bearing surface, the second write gap having at least a portion thereof aligned with the first write gap in a direction parallel to a direction of media travel thereover, wherein a common pole region extends from the first write gap to the second write gap and defines edges of the first and second write gaps;
• a second coil for generating the magnetic flux across the second write gap, the second coil being addressable independently of the first coil, the second coil having portions of several turns aligned in a direction about parallel to a media facing surface;
• wherein each of the write gaps is straight along an entire length thereof in a direction parallel to a media facing side thereof,
• the first and second write gaps being oriented at an angle relative to each other of greater than 0 degrees and less than 180 degrees,
• wherein the first and second coils are formed on a common substrate.

A method, comprising:

• forming a first write coil having portions of several turns aligned in a direction about parallel to a media facing surface;
• forming a first write gap;
• forming a second write gap having at least a portion thereof aligned with the first write gap in a direction parallel to a direction of media travel thereover;
• forming a second coil for generating a magnetic flux across the second write gap, the second coil being addressable independently of the first coil;
• and
• forming one or more write poles, wherein a contiguous region of one of the write poles that defines an edge of each of the first and second write gaps is formed concurrently,
• wherein the write gaps extend to opposite edges of the pole.
