FILE INDEX, METADATA STORAGE, AND FILE SYSTEM MANAGEMENT FOR MAGNETIC TAPE

摘要

In one embodiment, a computer program product for writing data to a magnetic recording tape includes a computer readable storage medium having computer readable program code embodied therewith. The computer readable program code includes: computer readable program code configured to cause a tape drive to: write a plurality of files to a first partition of a magnetic recording tape; and write an index to a second partition of the magnetic recording tape. The index includes information about locations of data of the plurality of files in the first partition of the magnetic recording tape. A longitudinal buffering band is present between the first and second partitions; and is configured to isolate writing in the first partition from overwriting neighboring tracks in the second partition. The longitudinal buffering band comprises an entirety of at least one full wrap of the magnetic recording tape.
