This arrangement ends in variable tape speed. As tape accumulates about the motorized takeup reel, the spool of tape little by little elevated in diameter, causing it pulling the tape through the recording head increasingly quicker.
Magnetic tape was released as a data-storage medium in 1951, when it had been Utilized in the auxiliary memory of UNIVAC I, the 1st digital computer generated for business use. For regarding the up coming ten years nearly all personal computers employed magnetic tape storage units. Through the nineteen sixties, having said that, magnetic disk and magnetic drum auxiliary Recollections began changing the tape models in substantial-scale scientific and business details-processing systems that have to have extremely speedy retrieval of stored data and plans.
Also, when the standard of electronic tape didn't progressively degrade with use in the tape, the Bodily sliding from the tape in excess of the heads and guides intended which the tape nevertheless did use, and eventually, that use would cause electronic mistakes and everlasting loss of high-quality if the tape was not copied ahead of reaching that time.
You can easily Lower the versatile magnet products using a scissors or utility knife to the specified size and condition of your job.

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。
Semi Joseph Begun also formulated the Stahltone-Bandmaschine steel six mm huge tape recorder in 1935. However, wire and metal tape was not a very good Remedy and would be replaced during the 1930s by skinny plastic tape, conceived by Fritz Pfleumer.
