The different spacings results in the first and third sensors and the second and fourth sensors having a cross-track spacing to accommodate for the effect of head skew. Each sensor is connected to an associated amplifier by a suspension trace and a common trace connected to its associated shield. Switching circuitry selects either the first and third amplifiers or the second and fourth amplifiers as the active pair depending on the radial location where the data is to be read. Thus the appropriate pair of sensors are aligned with the data tracks despite the presence of high head skew."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Two-dimensional magnetic recording (TDMR) disk drive with multiple sensors and circuitry for selection of an active pair of associated amplifiers","description":"A two-dimensional magnetic recording (TDMR) disk drive has a gas-bearing slider that includes first and second sensors with a first cross-track spacing electrically coupled to a first magnetic shield,","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9837106","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.
