摘要： A spherical projection portion for pivotally supporting a magnetic head is protrusively formed in a tongue piece formed in a flexure, and a non-contact portion with the slider are formed on both sides of the projection portion. The backward portion with the projection portion and the non-contact portion as a boundary is formed into a bonding portion. A bonding agent between the bonding portion and the slider is prevented from flowing toward a magnetic conversion element by the projection portion and the non-contact portion. Since the bonding agent is not present in the vicinity of the magnetic conversion element, the magnetic conversion element is not deformed due to the expansion and contraction of the hardened bonding agent. Also, since the bonding area is formed into an appropriate dimension, the protuberance dimension of a crown of the slider is not varied.
摘要翻译：用于枢转地支撑磁头的球形突出部分突出地形成在形成在弯曲部中的舌片中，并且与滑块的非接触部分形成在突出部分的两侧。具有突出部分和非接触部分作为边界的向后部分形成为接合部分。通过突出部和非接触部，防止接合部和滑块之间的接合剂朝向磁性转换元件流动。由于粘合剂不存在于磁转换元件附近，所以磁化转换元件不会由于硬化的粘合剂的膨胀和收缩而变形。此外，由于接合区域形成为合适的尺寸，所以滑块的凸起的突起尺寸不变。

摘要： A cobalt-base ternary alloy containing small amounts of hafnium and tantalum formed by sputtering, vapor deposition, etc., is used as the principal magnetic pole of a magnetic head for perpendicular magnetic recording, the core thin layers of a thin layer magnetic recording head, or the magnetic shield thin layers of a thin layer magnetic reproducing head. The ternary amorphous alloy has a high permeability and a high saturation magnetic flux density and hence the thickness of the foregoing layers composed of the alloy can be reduced as thin as possible.

The element unit has a fixed magnetic layer and a free magnetic layer laminated via a non-magnetic layer on the fixed magnetic layer. A magnetism direction of the fixed magnetic layer faces an element width direction (Y direction) of a sensitivity axis direction.
