    摘要： Magnetic data storage devices use read/write heads to transfer data between the magnetic storage medium and the rest of the system. The read head is constructed with a magnetic layer called a free layer whose magnetic axis rotates based upon external magnetic influences of the magnetic storage medium. The free layer is biased into a predetermined magnetic orientation with the magnetic influence of a layer called a hard bias layer. Orientation of magnetic axes within the hard bias layer is desired. This document describes a hard bias layer whose magnetization exhibits uniaxial magnetic anisotropy.

    摘要： An improved structure for the construction of perpendicular recording media is disclosed. The structure includes a tri-layer IML resident between a soft under layer CoTaZr film and a CoPtCr—SiO2 magnetic media. In an embodiment, the tri-layer comprises a RuxCr1-x layer over dual nucleation layers of Ni—Fe and Ni—Fe—Cr. The tri-layer replaces the typical Ru and Ni—Fe intermediate layers of the prior art, resulting in considerable improvement in lattice matching between the Ru containing intermediate layer and the CoPtCr—SiO2 magnetic media, further resulting in improved magnetic media performance.

    摘要： An integrated servo and read device implementing Extraordinary Magnetoresistive (EMR) sensors. In one embodiment, dedicated EMR sensors are employed: one for data reading and one for servo operations. The sensors are preferably configured in an abutted configuration. In addition to magnetic recording systems, the device is also useful in a magnetic imaging device such as a scanning magnetometer. The integrated device may also be useful in other devices requiring a high sensitivity, high resolution sensor.

    摘要： A contact magnetic transfer (CMT) method for forming a magnetic pattern, such as the servo pattern on a magnetic recording disk, uses a master template with antiferromagnetically-coupled (AF-coupled) magnetic islands. The template is a rigid or flexible substrate with each magnetic island being two ferromagnetic films antiferromagnetically-coupled by an antiferromagnetically-coupling (AFC) film. In the presence of the applied magnetic field the magnetic moments of the two ferromagnetic films are parallel and substantially identical so they generate a magnetic field that cancels the applied field in the region of the slave disk facing the islands. However, when the applied field is removed, any residual magnetization results in the remanent moments in the two ferromagnetic films being oriented antiparallel as a result of the antiferromagnetic exchange coupling across the AFC film. Thus the islands have no net remanent magnetic moment that can affect the servo pattern transferred to the recording disk.
