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： A method for synchronizing writing to a bit patterned media includes: reading bits from skipped blocks on the bit patterned media, using timing of bits read from the skipped blocks to update a write clock, and writing request data to physical blocks on the bit patterned media, interleaved with the skipped blocks. An apparatus that operates in accordance with the method is also provided.

摘要： An apparatus having a first pole with a first side and a second side opposite from the first side, a second pole positioned on the first side of the first pole, and a waveguide positioned on the second side of the first pole wherein the waveguide has an end adjacent to an air bearing surface. The first pole includes a first portion spaced from the waveguide and a second portion extending from the first portion to the air bearing surface, with the second portion being structured such that an end of the second portion is closer to the waveguide than the first portion.

摘要： A magnetic storage system includes a magnetic storage medium and a transducer positioned adjacent the magnetic storage medium. The transducer has a reader positioned adjacent writer and a reader bias coil located on the transducer. Transducer circuitry is configured to apply a bias signal to the reader bias coil during a read-write operation. The reader bias coil generates a reader bias field proximate the reader.
