Abstract:
In an approach to improve write transducers a write transducer for recording data on a magnetic media is disclosed. The write transducer comprises a first pole piece. The write transducer further comprises a second pole piece. The first pole piece and the second pole piece are arranged in such a way, that a write gap is formed between the first pole piece and the second pole piece. A longitudinal axis is defined between opposite ends of the write gap. A length of the write gap along the longitudinal axis varies in the direction transverse to the longitudinal axis.
