When the head is over a first data sector not being written, a first prelase bias is applied to the laser, and when the head is over a servo sector, a second, lower prelase bias is applied to the laser. When the head is over a second data sector being written, a write bias higher than the first prelase bias is applied to the laser."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device boosting prelase bias while over data sector for heat assisted magnetic recording","description":"A data storage device is disclosed comprising a disk comprising a plurality of data sectors and a plurality of servo sectors, and a head actuated over the disk, wherein the head comprises a laser conf","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9620162","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.
