    摘要： Methods and devices are provided for microwave-assisted magnetic recording with collocated microwave and write fields. An illustrative device includes a magnetic write pole and one or more alternating-field components. The magnetic write pole is configured for providing a magnetic write field. The one or more alternating-field components are disposed to at least partially coincide with the magnetic write pole. The one or more alternating-field components are configured to provide an alternating magnetic field having a microwave frequency and an orientation that is at least partially transverse to the magnetic write field.

    摘要： Data storage systems having barriers that may reduce erasure flux and increase write-ability are provided. Data storage systems include a writing element. The writing element has a write pole with a flare region. A magnetic flux barrier is located along the write pole flare region. The magnetic flux barrier is illustratively made from an in-plane magnetically anisotropic material that has an easy plane of magnetization. In another embodiment, a data storage system includes a writing element having an air bearing surface and a shield at the air bearing surface. The shield has a magnetic permeability of approximately zero. The shield illustratively includes alternating layers of positive and negative permeabilities. The shield optionally includes a plurality of shields that may include top, bottom, and side shields.

    摘要： A magnetic recording head includes a write pole and a first permanent magnet. The write pole has a write pole tip, a leading edge, a trailing edge, a first side and a second side. The first permanent magnet is located either at the trailing edge of the write pole, the first side of the write pole or at the second side of the write pole. The first permanent magnet has a magnetization orientation that is changed in relation to a field of the write pole.
