Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark.

Magnetic tape provides a compact, economical means of preserving and reproducing varied forms of information. Recordings on tape can be played back immediately and are easily erased, permitting the tape to be reused many times without a loss in quality of recording.

An audio tape recorder, also known as a tape deck, tape player or tape machine or simply a tape recorder, is a sound recording and reproduction device that records and plays back sounds usually using magnetic tape for storage.

Magnetic recording, which is today used for video and audio tape, was first introduced around 1899-1900 by the Danish inventor Valdemar Poulsen. Poulsen envisioned that it would be useful for office dictation and telephone recording, but his “Telegraphone,” manufactured in the U.S. and Europe by various firms, never took off.

2020年3月4日 · Types of magnetic storage devices would be the floppy disc, hard disks, magnetic recording tapes, cassette tapes and the magnetic chips that allow cashless transactions via ATM, credit and debit cards.

2023年7月28日 · Magnetic wire recording, and its successor, magnetic tape recording, involves using a magnetizable medium that moves past a recording head. An electrical signal, which is analogous to the sound to be recorded, is fed to the recording head, inducing a pattern of magnetization similar to the signal.

The magnetic sound recording technology began and enabled the digital technology. In 1967 the first digital audio magnetic tape recorder was developed and by 1982 the first compact discs (CDs) are marketed by Philips and Sony.

The methods employed in recording data on to the magnetic tape include direct recording, frequency modulation (FM) and pulse code modulation (PCM). Modulation of the current in the recording head by the signal to be recorded linearly modulates the magnetic flux in …

New and exciting field of electricity and magnetism provided them the way to create new wave of sound recording and playback devices that would became one of the most popular sound carrying media in the world.

Principles of Magnetic Recording 6-19 Several researchers extended the high-frequency response of magnetic recorders to include the wide bandwidth of a (then monochromatic) television video signal.
