Curie point writing and Kerr signal reading in magneto-optical disk media are accomplished with a flint glass single-mode fiber that connects the optical source (laser diode)–detector and the magneto-optical medium. The Kerr signal is detected sensitively with high stability against external disturbances such as stress and deformation of the fiber. This technique offers a simple, flexible, light, movable, and remotely settable means for signal processing of magneto-optical devices.
