    Abstract: A data writer can be configured with at least a write pole separated from a front shield by a non-magnetic gap layer. The front shield may consist of at least a seed layer and a shielding layer with the shielding layer having an easy axis coercivity along a first direction of 4 Oe or more and a hard axis coercivity along a second direction of 0.5 Oe or more.

    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.

    Abstract: A magnetic element can have at least a write pole configured with a write pole tip that has a tip surface oriented at a first angle with respect to an air bearing surface (ABS), a first bevel surface extending from the ABS and oriented at a second angle with respect to the ABS, and a second bevel surface extending from the ABS and oriented at a third angle with respect to the ABS. The first, second, and third angles may be configured to be different and non-orthogonal to each other.
