The C_bot is made of TiO2 or Al-doped TiO2, for example, with a dielectric constant >10. As a result, the writer behaves like a 1+1T writer at lw frequencies substantially below 1 GHz, as a 1+0.xT writer at lw frequencies proximate to 1 GHz, and like a 1+0T writer in an overshoot region of the lw. Accordingly, better trailing shield field gradient, signal-to-noise ratio, and bit error rate during high frequency operation are achieved without compromising saturation speed and adjacent track interference for an overall improvement in performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive one turn (C1T) perpendicular magnetic recording (PMR) writer designs","description":"A PMR writer with a capacitive one turn design is disclosed with a one turn top coil above the main pole (MP), a one turn bottom coil below the MP, and where a capacitor (C_bot) is electrically connec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11264051","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.
