When a voltage value of a power supply voltage falls below a first threshold, the motor driver starts a retract operation of retracting the magnetic head to the ramp by controlling a voltage applied to the motor. When the voltage value of the power supply voltage falls below a second threshold larger than the first threshold, the processor transmits an instruction related to applying a brake to the movement of the magnetic head to the motor driver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic disk device","description":"According to an embodiment, a magnetic disk device includes a magnetic disk, a magnetic head that accesses the magnetic disk, a motor that moves the magnetic head, a ramp, a motor driver, and a proces","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11948604","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.
