A method comprises the step of providing a read-write element on a wafer including at least one magnetoresistive stripe, providing a shared pole layer above the magnetoresistive stripe, and planarizing the shared pole layer. Thereafter, a top pole layer is formed above the shared pole layer. Together, the shared and top pole layers form the write element. Because the shared pole layer is planarized, the gap portion of the write element between the shared and top pole layers is flat. Because of this, improved recording density can be achieved.
