The LS2 layer has a notch filled with dielectric material at the air bearing surface (ABS) that extends to a height≤h1, or may be completely replaced with dielectric material. Two notch front sides each form an angle β with the LS1 bottom surface, and two notch inner sides between the ABS and LS2 backside form angle δ with the ABS where each of β and δ is from 10 degrees to 170 degrees. Accordingly, bits per square inch performance is improved while substantially maintaining tracks per square inch capability for an overall gain in area density capability."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optimization of high damping shield geometry in perpendicular magnetic recording (PMR) writer","description":"A PMR writer is disclosed with a leading shield in which a lower (LS2) layer, a middle LS1 layer, and an upper leading edge taper (LET) layer have a damping parameter≥0.04, and extend from an air bear","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10490210","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.
