Claims
- 1. A magneto-optical recording medium on a base comprising:
- a magneto-optical recording layer being formed on the base and being formed of a TbFeCo amorphous alloy;
- a first layer of a FeCoCr alloy being formed on said magneto-optical recording layer;
- a second layer of Tb being formed on said first layer; and
- both the first layer and the second layer each having a thickness of between 10 .ANG. and 50.ANG..
- 2. A magneto-optical recording medium on a base comprising:
- a magneto-optical recording layer being formed of a TbFeCoCr amorphous alloy and being formed on the base;
- a first layer of FeCoCr alloy being formed on said magneto-optical recording layer;
- a second layer of Tb being formed on said first layer; and
- each of said first and second layers having a thickness in a range of 10 .ANG. to 50 .ANG..
- 3. A magneto-optical recording medium comprising:
- a magneto-optical recording layer formed of an amorphous alloy selected from a group consisting of TbFeCo amorphous alloy and TbFeCoCr amorphous alloy,
- a first protective layer being formed on a surface of said magneto-optical recording layer, said first protective layer being an alloy of transition metal elements, and
- a second protective layer consisting of Tb being formed on said first protective layer.
- 4. A magneto-optical recording medium according to claim 3, wherein said first protective layer is a FeCoCr alloy.
- 5. A magneto-optical recording medium according to claim 3, wherein each surface of the recording layer is covered by the first protective layer and each first protective layer is covered by a second protective layer.
- 6. A magneto-optical recording medium according to claim 3, wherein each of said first and second protective layers has a thickness in a range of 10 .ANG. to 50 .ANG..
- 7. A magneto-optical recording medium according to claim 6, said first layer having a thickness between 10 and 50 .ANG..
- 8. A magneto-optical recording medium according to claim 5, wherein each of said first and second protective layers has a thickness of between 10 .ANG. and 50 .ANG..
- 9. A magneto-optical recording medium according to claim 7, said second layer having a thickness between 10 and 50 .ANG..
- 10. A magneto-optical recording medium according to claim 8, wherein each first protective layer is a FeCoCr alloy.
