The mapping maps the first logical unit to the physical memory locations of the first set of surfaces and a parasitic portion of the second set of surfaces, and maps the second logical unit to the physical memory locations of the second set of surfaces exclusive of the parasitic portion of the second set of surfaces. Thus, data transfer commands performed on the parasitic portion are executed by one actuator while credit is given to the logical unit associated with the other actuator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Parasitic commands for equalizing logical unit capacity in asymmetric multiple actuator hard disk drive","description":"A multiple-actuator hard disk drive includes a first actuator associated with a first logical unit and configured to operate on a first set of disk surfaces, a second actuator associated with a second","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11954027","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.
