发明名称 Magneto-optic recording medium with reduced demagnetizing field threshold
摘要 A magneto-optic recording medium having a reduced demagnetizing field threshold incorporates a thin recording layer having a thickness of less than or equal to approximately 15 nm, and preferably less than or equal to approximately 12 nm. The recording medium thereby exhibits a demagnetizing field threshold of less than or equal to approximately 150 Oe, and preferably less than or equal to approximately 120 Oe. Dielectric and reflective layers in the recording medium stack are tuned to achieve acceptable optical and magnetic characteristics for write and readout operations. The reduced demagnetizing field facilitates use of the recording medium in recording applications that use small magnetic fields for recording and erase. The recording medium is particularly useful in near-field, air-incident recording applications employing magnetic field modulation recording techniques.
