Keyword-Based File Migration Ordering for Faster Tape Access

The patent applies local quality by differentiating file placement locations on the tape based on access frequency characteristics. Frequently accessed files (identified by keyword density) are positioned at optimal locations closer to the tape reader, while less frequently accessed files are placed in other areas. This creates non-uniform quality distribution across the tape storage medium, optimizing access speed for critical files while maintaining high storage capacity.

The patent segments the tape storage medium into different zones based on proximity to the tape reader. The analysis module divides files into categories based on keyword density, and the ordering module places different segments of the file set into different physical zones on the tape. This segmentation allows the system to optimize access speed for high-priority files in accessible zones while utilizing distant zones for lower-priority files, thereby maintaining overall storage capacity.

The system implements self-service by automatically performing natural language processing and keyword extraction on files during the migration process. The analysis module autonomously analyzes file contents, extracts keywords, determines keyword density, and generates ordering information without requiring manual intervention. This self-service approach manages the processing complexity internally while delivering the benefit of optimized file placement for faster access.
