METHOD FOR PRODUCING BI-POLAR COMPLEMENTARY STRUCTURE PATTERNS |
| 摘要 |
The embodiments disclose a method including creating at least one first structure including magnetically isolated features in servo fields, and creating at least one second structure including finger-structure patterns including intentional weak nucleation points in servo fields to create a regular bi-polar magnetization direction after bulk DC initialization, and wherein the first and second structures form bi-polar complementary structure patterns. |
