The method also includes storing the HRTD as part of end of data (EOD) of the index partition in response to a tape cartridge housing the tape medium being unloaded. The storing the HRTD as part of the EOD of the index partition includes requesting movement of the tape medium to the index partition in order to update an index file after changes have occurred to data in the data partition, writing an updated index file into the index partition concurrent to writing an updated HRTD into the EOD of the index partition, and requesting for the tape cartridge to be unloaded."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High resolution tape directory (HRTD) stored at end of data in an index partition","description":"In one embodiment, a method includes writing a file into a data partition of a tape medium, writing a pointer of the written file in an index partition and creating a high resolution tape directory (H","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9842623","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.
