Several different metrics can be utilized including a normalized norm metric, a normalized cross correlation metric, and a cross correlation with detected data metric. These metrics can be utilized to determine off-track shift of one or more read heads such that the read head position can be corrected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital data driven position error signal for magnetic recording","description":"Various embodiments provide the position error signal (PES) that is generated by the data read channel that uses internal signals such as analog-to-digital signals, recovered data bits and signals or ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9837110","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.
