Self biasing thermal magneto-optic medium |
摘要 |
A layer in a magnetic storage medium provides a biasing magnetic field for writing data. The layer exhibits a net magnetization with an orientation in a first direction when the layer is at a temperature below its compensation temperature and a net magnetization with an orientation in a second direction different from the first direction when heated as by a laser to a temperature above its compensation temperature, but below its Curie point temperature.
