    • A magnetic head includes first and second magnetic yoke layers which contact each other at a back closure region at one end and delineate a transducer gap at another end. A toroidal coil encompasses one of the yoke layers. The coil axis of the toroidal coil passes through the encompassed yoke layer. During data writing, electrical current passes through the toroidal coil inducing magnetic flux along the coil axis, which flux is efficiently and directly delivered to the transducer gap for writing on a recording medium. During data reading, magnetic flux intercepted by the transducer gap flows along the encompassed yoke layer and efficiently induces electrical current in the toroidal coil for amplification. In alternative embodiments, separate read transducers are disposed adjacent to the toroidal coils to form merged heads.
    • 磁头包括在一端的后闭合区域彼此接触并在另一端描绘换能器间隙的第一和第二磁轭层。 环形线圈包围磁轭层之一。 环形线圈的线圈轴线穿过所包围的轭铁层。 在数据写入期间,电流通过环形线圈,引起沿着线圈轴的磁通量,该磁通有效地并直接传递到换能器间隙,以便在记录介质上进行写入。 在数据读取期间,由换能器间隙截取的磁通量沿着包围的磁轭层流动,并有效地在环形线圈中感应出电流用于放大。 在替代实施例中,单独的读取换能器被布置成与环形线圈相邻以形成合并的头部。

    • A magnetic head assembly includes a magnetoresistive (MR) read sensor dielectrically disposed between a magnetic shield layer and a first pole layer. A write transducer comprises an inductive coil having a plurality of windings dielectrically disposed between the first pole layer and a second pole layer. The magnetic shield layer partially overlaps portions of the coil windings. A nonmagnetic layer is coplanar with the magnetic shield layer. A reduced coupling area between the magnetic shield layer and the coil decreases the mutual inductance applied to the magnetic coil by the magnetic layer, resulting in the coil having better response to write current and being capable of operating at wider frequency ranges. The first pole layer includes a unique shape having a narrow mid-section integrally formed between the wider end sections. The narrow mid-section of the first pole layer also reduces the coupling area between the first pole layer and the coil and reduces the mutual inductance from the first pole layer to the coil.
    • 磁头组件包括介电地设置在磁屏蔽层和第一极层之间的磁阻(MR)读取传感器。 写入传感器包括感应线圈,该感应线圈具有多个绕组,所述绕组介电地设置在第一极层和第二极层之间。 磁屏蔽层部分地与线圈绕组的部分重叠。 非磁性层与磁屏蔽层共面。 磁屏蔽层和线圈之间的减小的耦合面积降低了由磁性层施加到磁性线圈的互感,导致线圈对写入电流具有更好的响应并且能够在更宽的频率范围内操作。 第一极层包括具有在较宽端部之间整体形成的窄中间部分的独特形状。 第一极层的窄中间部分还减小了第一极层和线圈之间的耦合面积,并且减小了从第一极层到线圈的互感。
