The two heating sources create a protrusion profile relative to the undistorted ABS that recesses the read element and main write pole at the track center line relative to off-track positions. The resulting DFH control also protects the head from HDI (head-disk interference) events that are either the result of calibration procedures or normal HDD (hard disk drive) operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic flying height read/write head with off-track contact capability at touch down in hard disk drives","description":"Dynamic fly height (DFH) control is obtained for a read/write head by use of a heating element having two laterally separated heat sources symmetrically spaced around the track center line of the head","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9659584","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.
