摘要： PROBLEM TO BE SOLVED: To provide a longitudinal bias stack for a current-perpendicular-to-plane (CPP) read sensor.SOLUTION: A read head having an improved longitudinal bias stack is provided to stabilize a detection layer structure of a CPP read sensor. The longitudinal bias stack is separated from the CPP read sensor by an insulating layer in two side regions, and sandwiched together with the insulating layer and the CPP read sensor between upper and lower ferromagnetic shields in the read head. According to the preferred embodiment, the longitudinal bias stack mainly includes a Fe-Pt longitudinal bias layer having no seed layer, and hence an spacing between the Fe-Pt longitudinal bias layer and the CPP read sensor is determined based on only a thickness of the insulating layer. The Fe-Pt longitudinal bias layer having no seed layer exhibits good in-plane hard magnetic properties after annealing, and the spacing is narrow. Thus, this stabilizing scheme is effective.
摘要翻译：要解决的问题：提供用于电流 - 垂直平面（CPP）读取传感器的纵向偏置堆叠。解决方案：提供具有改进的纵向偏置堆叠的读取头，以稳定CPP读取传感器的检测层结构。纵向偏置叠层通过两侧区域的绝缘层与CPP读取传感器分离，并与读取头中的上下铁磁屏蔽之间的绝缘层和CPP读取传感器夹在一起。根据优选实施例，纵向偏置堆叠主要包括不具有种子层的Fe-Pt纵向偏置层，因此仅基于厚度来确定Fe-Pt纵向偏置层和CPP读取传感器之间的间距绝缘层。没有种子层的Fe-Pt纵向偏置层在退火后表现出良好的面内硬磁性能，间隔窄。因此，这种稳定方案是有效的。

摘要： PROBLEM TO BE SOLVED: To provide a thin-film magnetic device in which permeability can be enhanced easily in the high frequency region. SOLUTION: At least on the surface or the backside of a lower magnetic film 11 and an upper magnetic film 14, flaw-like grooves 16 and 17 are formed to extend along the extending direction of a coil 13 (e.g., the Y axis direction which is the extending direction of a second coil pattern). In the region for forming the flaw-like grooves 16 and 17 (the region for forming the lower magnetic films 11B, 11D and the upper magnetic films 14B, 14D), the direction of anisotropic magnetization Mb, Md is controlled and displacement (rotation) of the direction of anisotropic magnetization Mb, Md is pinned by means of the flaw-like grooves 16 and 17. Consequently, some permeability is sustained even in the high frequency region. Production process is not complicated by formation of such flaw-like grooves 16 and 17. COPYRIGHT: (C)2008,JPO&INPIT
