磁場中熱処理による薄膜磁気ヘッドの特性改善

抄録

  Behavior of characteristics in CoNbZr amorphous thin film heads by magnetic field annealing is investigated by observing the domain patterns. Two step magnetic field annealing in which the magnetic field is applied first perpendicularly to the preferable easy axis and secondly in parallel with it, is found to be effective to improve the characteristics of the heads.
