Magnetic head having write head with double split yoke
摘要:
The magnetic head of the present invention includes a P1 pole having an opening formed therethrough, and a P2 pole that is formed over the opening. A second magnetic pole tip is positioned relative to the first magnetic pole such that the first magnetic pole is symmetrically disposed relative to the second magnetic pole tip. Induction coils may be helically wound around portions of the first and/or second magnetic poles, or, alternatively, a planar, spiral induction coil may be fabricated for use with the first and second magnetic poles. An enhanced embodiment includes a first magnetic pole tip piece having a length that defines the throat length of the magnetic head and a thickness that increases the gap at rearward portions of the second magnetic pole tip of the magnetic head.
