A method in one embodiment includes forming a first write coil; forming a first write gap; forming a second write gap; forming a second coil for generating a magnetic flux across the second write gap, the second coil being addressable independently of the first coil; and forming one or more write poles, wherein a write pole region adjacent the first and second write gaps is formed concurrently."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tandem magnetic writer with independently addressable coils","description":"A magnetic head in one embodiment includes a pole; a first write gap in the pole; a first coil for generating a magnetic flux across the first write gap; a second write gap in the pole having at least","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526138","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
