Abstract
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.
Claims20
A magnetic storage system comprising:
- a magnetic storage medium;
- a transducer adjacent the positioned magnetic storage medium, the transducer having a reader adjacent a writer, and a reader bias coil;
- and
- circuitry configured to apply a reader bias signal to the reader bias coil during a read-write operation.
1 more element
A method of writing data to a magnetic storage medium, comprising:
- applying a write signal to a writer of a transducer and generating a write field applied to the storage medium, the writer positioned proximate a reader of the transducer;
- applying a reader bias signal to a reader bias coil, the reader bias coil positioned proximate a reader of the transducer and producing a bias magnetic field which opposes the write field proximate the reader;
- and
- reading data from the storage medium with the reader while writing data to the storage medium with the writer.
