In an embodiment of the present invention, an HDC/MPU sequentially performs data writing and reading while increasing heater power. The HDC/MPU further determines whether or not a head slider has retrieved the data properly. When the data cannot be retrieved properly, the HDC/MPU specifies a heater power value in a normal operation based on the heater power value at which the data could not be retrieved properly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for specifying control value for controlling clearance adjustment amount between head and disk, disk drive device and manufacturing method thereof","description":"Embodiments of the present invention help to reduce damage of a head element portion or a magnetic disk in a procedure for specifying a heater power value for adjusting a clearance between the head el","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537488","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.
