Perpendicular Magnetic Recording Medium and Magnetic Recording Apparatus |
摘要 |
A discrete track medium and a bit patterned medium with a high SNR are manufactured at low cost. A seed layer and a recoding layer are formed on a bottom surface and a side wall of a groove portion, which is formed between non-magnetic projected structures artificially patterned. Then, the recording layer on the projected portion is removed.
