Protecting information written to recording medium |
摘要 |
A method of protecting information written to a recording medium includes magnetizing the recording medium to form a first magnetic pattern corresponding to information to be stored, and magnetizing the recording medium to form a protective magnetic pattern having a phase difference of 180° from the first magnetic pattern at a position adjacent to where the first magnetic pattern is formed, with adjacent bits of the first magnetic pattern opposite and the protective magnetic pattern opposite to each other. |
