Magnetic bubble memory device |
摘要 |
A magnetic bubble memory device has two types of magnetic bubble propagation tracks. One type of magnetic bubble propagation tracks are formed by implanting ions into a magnetic layer. The other are formed by a soft magnetic material, for example, a permalloy. At least the area where the soft magnetic material is located has a smaller thickness than the other area.
