Stable magneto optic recording medium |
摘要 |
Magneto-optic recording media have been made more resistant to corrosion by incorporating small amounts of tantalum and/or yttrium into the rare earth-transition metal active layer of the recording media. This improvement should help make magneto-optic media more reliable in the long term storage and retrieval of information.
