Combined thin film magnetoresistive read, inductive write heads

Using photolithographic and thin-film deposition techniques various types of single- and multi-turn inductive heads have been fabricated, with or without a magnetoresistive (MR) element in the gap. The MR element has a Barberpole configuration, which makes biasing by an external field superfluous. Reading has also been done inductively. Read and write experiments have been performed on tape and disc.
