The magnetic tape may be the oldest memory media for desktops, still in use today. Made in Germany in 1928 although not applied right until 1951 inside the Mauchly-Eckert UNIVAC I computer, the magnetic tape was produced for audio storage and makes use of the magnetic wire recording principle.
As the tape moves more than the recording head, The pinnacle's magnetic discipline varies While using the sound Hence varying the magnetism on the passing particles of metal oxide on the tape.[eleven]

This innovation was an awesome driving pressure driving the explosion of common songs from the late nineteen fifties and 1960s.[citation desired]
Scientific experiments that develop mass quantities of data in some microseconds leverage tape's capability and produce speeds.
保磁力の優れた非酸化金属磁性体（オキサイド）が蒸着されており高密度の記録に適する。大量複製時のマザーテープとしても使用されるがメタルポジションテープ自体は転写法による大量複製には適さない。
While in the eighties, several makers manufactured specified tape formulations blending polyurethane and polyester as backing material which tended to soak up humidity around a few years in storage and partially deteriorate.

A side-outcome of slicing the tape at an angle is usually that on stereo tapes the edit occurs on one particular channel a split-2nd before the other. Lengthy, angled splices can even be used to make a perceptible dissolve from a single audio to the following; periodic segments can mag tape induce rhythmic or pulsing consequences.[5] Using reels to produce and gather the tape makes it simple for editors to manually go the tape back and forth over the heads to seek out the precise point they need to edit. Tape to be spliced is clamped in a very splicing block connected on the deck near the heads to hold the tape correctly when the edit is designed. The Editall was a long-in-creation splicing block, named for its inventor Joe Tall, a tape editor at CBS.[six]
