  • Write head having reduced dimensions
    Patent number: 9153257
    Abstract: A write head having reduced dimensions. In one implementation, the write head has a main pole having a leading side and a trailing side, a leading yoke on the leading side of the main pole, and a coil wrapped around the main pole and the leading yoke. The coil on the leading side and the leading yoke having a distance of no greater than 300 nm therebetween, and the coil on the trailing side and the main pole having a distance of no greater than 350 nm therebetween. In an alternate implementation, the write head has a trailing yoke, with the coil on the trailing side and the trailing yoke having a distance of no greater than 350 nm therebetween.
