The top's electromagnet coil translates the different magnetism into electrical signals which were despatched to another amplifier circuit that will electricity a speaker or headphones, earning the recorded sound audible.[11]
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。
