tape stacking

Tape stacking is a method for optimizing the capacity of storage space on magnetic tapes. In normal data storage on magnetic tape, the tapes are not sufficiently utilized due to label 1 storage. Due to the unique assignment of the storage address, each stored file, regardless of its size, requires its own magnetic tape.

The tape stacking method uses almost 100% of the storage space on the magnetic tapes and thus reduces the number of magnetic tapes to be managed. Tape stacking, which is part of storage management, sorts, consolidates, and stores files according to a variety of criteria. Bypassing the Label 1 issue, files are sorted by location, volume or file attributes and consolidated into a logical record.

Tape stacking is recommended when changing media and can result in a significant reduction in magnetic tapes for tape libraries such as the Automated Tape Library( ATL).
