Patent number: 8422159Abstract: 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.Type: GrantFiled: June 4, 2009Date of Patent: April 16, 2013Assignee: Seagate Technology LLCInventors: Kaizhong Gao, Alexandru Cazacu, Robert William Lamberton, Michael Leigh Mallary

Publication number: 20100061019Abstract: 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.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Inventors: Mourad Benakli, Michael Leigh Mallary
