The number of the read-write heads is preferably sufficiently large so that the read-write heads cover all tracks on the one or more rotating platters. In one embodiment, a disk includes a rotatable platter, a central spindle to rotate the rotatable platter arounds an axis, an electric motor to drive the central spindle, and multiple read-write heads mounted over the rotatable platter. In one embodiment, the platter includes multiple tracks arranged in form of concentric circles, where each of the read-write heads performs read-write operations on one of the tracks, and each track is assigned at least one of the multiple read-write heads."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Disk drive with multiple read-write heads","description":"The embodiments of the invention improve the traditional disk drives by eliminating the mechanical actuator assembly that moves the read-write head attached to the actuator assembly, and replacing it ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9728212","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.
