Magnetic recording head with trailing shield having multiple throat-heights
Abstract:
The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a main pole and a trailing shield disposed adjacent to the main pole. A recessed edge of the trailing shield has throat heights varying in the cross-track direction. In one embodiment, the central portion of the trailing shield has a first throat height greater than a second throat height of outer portions of the trailing shield. The trailing shield having varying throat heights in the cross-track direction strengthens the writing capability or improves the XTI of the magnetic recording head.
