An enclosure base may include a curved slot in which the pin is disposed, where one end of the slot may correspond to the head slider being near the inner diameter of a first disk stack and the other end of the slot may correspond to the head slider being near the inner diameter of a second disk stack adjacent to the first disk stack. The magnet may be disposed within or adjacent to the curved slot, at a midway location, whereby the pin is held in place by the magnet at a position that corresponds to the head slider being parked on a ramp positioned between the disk stacks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Actuator limiters for multiple disk-stack, shared actuator hard disk drive","description":"An actuator rotational limiter mechanism for a multiple disk-stack, shared actuator hard disk drive includes an actuator comb with a protruding pin, whereby rotation of the actuator comb is limited by","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9704521","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.
