    • A reader structure, a method of biasing a free layer of a reader structure, and a read head are provided, the reader structure comprises a free layer having a reader edge for interacting with and being proximal to a magnetic media; a first magnetic bias member and a second magnetic bias member each provided adjacent to the free layer, the first and second magnetic bias members being configured to have a first magnetisation direction which is substantially parallel to the reader edge; an additional bias member disposed adjacent to the free layer, the additional bias member further being located proximal to at least one of the first magnetic bias member and the second magnetic bias member, and the additional bias member being configured to have a magnetisation direction that is substantially orthogonal to the first magnetisation direction.
    • 提供读取器结构,偏置读取器结构的自由层的方法以及读取头,所述读取器结构包括具有读取器边缘的自由层,所述读取器边缘用于与读取器结构的自由层相互作用并接近 磁性媒体; 第一磁性偏压构件和第二磁性偏压构件,每个设置成与所述自由层相邻,所述第一和第二磁性偏压构件配置为具有基本平行于所述读取器边缘的第一磁化方向; 附加的偏置构件,所述附加的偏置构件设置为与所述自由层相邻,所述附加的偏置构件还位于所述第一磁性偏置构件和所述第二磁性偏置构件中的至少一个的附近,并且所述另外的偏置构件被配置为具有磁化方向, 基本上正交于第一磁化方向。
