Abstract
The present invention describes a write element for a magnetic recording device that incorporates a second pole pedestal with a tapered shape. This tapered shape substantially reduces side-writing and the second pulse effect, each of which can limit maximum areal densities of information recorded on magnetic media. The present invention further includes a magnetic recording device incorporating a write element with a tapered second pole pedestal within the read/write head. The present invention also includes a method for producing a write element incorporating a tapered second pole pedestal.
