Shield structure for reducing the magnetic induction rate of the trailing shield and systems thereof

A method, comprising:

• depositing a magnetic material as a stopper film above a substrate;
• forming an insulating material above the stopper film;
• depositing a hard film above the insulating material, the hard film leaving a portion of the insulating material exposed;
• forming a groove in the exposed insulating material for use in forming a main magnetic pole;
• depositing a paramagnetic film in the groove to form side gaps;
• forming a magnetic material in the groove above the side gaps for use as the main magnetic pole;
• planarizing an upper surface of the main magnetic pole, the hard film, and the side gaps;
• removing the insulating layer;
• plating a magnetic material on sides and above the main magnetic pole, the hard film, and the side gaps to form side shields;
• planarizing the side shields to a desired position consistent with an upper surface of the side gaps;
• forming a resist mask above each of the side shields;
• milling the main magnetic pole to a desired position relative to the side shields;
• removing the resist mask;
• removing residual portions of the side gaps that are positioned above an upper surface of the main magnetic pole;
• removing portions of the side shields on either side of the side gaps for use in forming a trailing shield (TS) gaps;
• depositing an insulating layer above the main magnetic pole, the side gaps, and the side shields where the portions of the side shields have been removed to form a trailing gap and TS gaps;
• and
• forming a magnetic material above the side shields, the trailing gap, and the TS gaps to form a trailing shield.
