Tape can accommodate numerous parallel tracks, allowing for not just stereo recordings, but multitrack recordings too. This gives the producer of the final edit Considerably increased flexibility, allowing for a efficiency for being remixed extensive once the general performance was originally recorded.

g., a push professing a compressed potential of five hundred GB might not be sufficient to again up 500 GB of genuine facts. Details that is definitely presently saved competently may well not enable any sizeable compression as well as a sparse databases may possibly supply much larger things. Program compression can realize a lot better outcomes with sparse data, but uses the host Pc's processor, and will slow the backup if the host computer is struggling to compress as fast as the information is created.[citation needed]
From the nineteen eighties, numerous companies created specified tape formulations blending polyurethane and polyester as backing substance which tended to absorb humidity more than a few years in storage and partly deteriorate.

So an organization wouldn't need to rely on tape for its newest backup. In addition, an organization need to make certain its tape library is appropriate with the remainder of its infrastructure.
前述のオートチェンジャーを使っていない場合は記録媒体がオンラインではない、つまり稼働中のシステムから物理的に隔離している前提のストレージなので、ネットワークを通じた不正アクセスやクラッキングが起こる心配がなく、コンピューターウィルスなどにネットワークにつながったシステムを全て破壊されてしまっても復旧が可能である。（このような特徴を、セキュリティ業界では「エアギャップ」と言う。）。オートチェンジャーで任意のテープを交換できる場合は不正アクセスによるクラッキングが行える可能性はある。
This permits for a temporary and reversible attachment or fastening, which makes it a practical Remedy for many predicaments. Magnetic tape's non-permanence is usually a appealing aspect, specially when you will need a flexible and detachable technique of securing or attaching objects.
