摘要： The object of the present invention is to provide a magnetoresistive magnetic head having good, stable playback characteristics. In an MR head wherein an MR element is interposed between a lower shield layer and an upper shield layer, separated by non-magnetic layers. The lower shield layer and the upper shield layer are formed from a material having high permeability and high resistivity. Since the magnetic shield layers are formed from materials having high permeability and high resistivity, even if friction causes dragging of the head surface, there is effectively no short circuit between the magnetic shield layer and the magnetic element.
摘要翻译：本发明的目的是提供一种具有良好稳定播放特性的磁阻磁头。在MR磁头中，MR元件介于由非磁性层分离的下屏蔽层和上屏蔽层之间。下屏蔽层和上屏蔽层由具有高磁导率和高电阻率的材料形成。由于磁屏蔽层由具有高磁导率和高电阻率的材料形成，所以即使摩擦导致磁头表面的拖动，磁屏蔽层和磁性元件之间也不存在短路。

摘要： A magnetic head device having excellent sliding contact between its slider surface and magnetic tape at the time of scanning is provided. This magnetic head device has a base member, a thin-film magnetic head formed in contact with the base member and accommodated in a non-magnetic layer with the top end of a magnetic gap being exposed, and an auxiliary member which sandwiches the non-magnetic layer between the auxiliary member and the base member. On the top ends of the base member, the non-magnetic layer, and the auxiliary member, a slider surface on which magnetic tape slides is formed in the aligning direction of the base member, the non-magnetic layer, and the auxiliary member, or in a direction inclined at a predetermined angle to the aligning direction. Accordingly, the non-magnetic layer can be made thin, and the area of the non-magnetic layer on the slider surface is small. Thus, the space between the magnetic head device and the magnetic tape can be made small, and the sliding contact of the magnetic head device can be improved.

摘要： A non-magnetic layer is laminated on a lower magnetic layer. A first upper magnetic layer is formed on the non-magnetic layer so as to form a magnetic core together with the lower magnetic layer and the non-magnetic layer. The first upper magnetic layer has a first saturation magnetic flux density and a first magnetostriction constant. An insulation layer is formed on the non-magnetic layer. A thin film coil is provided in the insulation layer. A second upper magnetic layer is formed on the insulation layer so as to be at least above the thin film coil. The second upper magnetic layer has a second saturation magnetic flux density and a second magnetostriction constant. The first saturation magnetic flux density is higher than the second saturation magnetic flux density. The second magnetostriction constant is lower than the first magnetostriction constant.
