发明名称 Multiple writing process for magnetic bit-patterned media
摘要 Two pass writing system and method for patterned media. In a first step, a write head of a hard disk drive writes with a strong write field. In a second step, a write head of the hard disk drive writes with a weak field. In this manner, magnetic islands of patterned media are written in the first step. In the second step, only those magnetic islands with a low switching field are written.
