Methods for tunable plating seed step coverage

A writer main pole for a perpendicular magnetic recording system is provided. The writer pole has a tunable bottom gap to side gap ratio, and may be formed using deposition of a first seed layer through an ion beam deposition process, deposition of a second seed layer through a physical vapor deposi...

Zusammenfassung:A writer main pole for a perpendicular magnetic recording system is provided. The writer pole has a tunable bottom gap to side gap ratio, and may be formed using deposition of a first seed layer through an ion beam deposition process, deposition of a second seed layer through a physical vapor deposition process, and deposition of a non-magnetic gap layer through a chemical vapor deposition process.
