  • Magnetic recording head with dielectric layer separating magnetic pole tips extensions from the zero throat coil insulator
    Patent number: 6775098
    Abstract: A magnetic recording head includes a zero throat formed on a bottom pole layer and a dielectric layer formed over a portion of the bottom pole layer and over a portion of the zero throat. A bottom pole extension, a gap layer, and a top pole extension are plated in a pole tip region of the recording head so that the dielectric layer separates the plated layers in the pole tip region from the zero throat. The dielectric layer reduces the magnetic flux leakage between a bottom pole extension and a top pole extension of the recording head.
