Thereby, the pivot and VCM tilt and the coil torsion modes of the direct plant transfer function are minimized and the peak-to-peak gain in the coil torsion mode of the coupled plant transfer function is reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Anchoring structure for improved structural dynamics of actuators in a multi-actuator hard disk drive","description":"A multi-actuator hard disk drive includes a lower actuator with a corresponding voice coil motor assembly (VCMA) including a magnet coupled with a first magnet housing plate, a coaxial upper actuator ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11942121","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.
