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. Devices that use magnetic tape can with relative ease record and play back audio, visual, and binary computer data.
Magnetic tape brought about sweeping changes in both radio and the recording industry. Sound could be recorded, erased and re-recorded on the same tape many times, sounds could be duplicated from tape to tape with only minor loss of quality, and recordings could now be very precisely edited by physically cutting the tape and rejoining it.
A reel-to-reel tape recorder from Akai, c. 1978. 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 tape was commonly used to create master copies.. Mastering, a form of audio post production, is the process of preparing and transferring recorded audio from a source containing the final mix to a data storage device (the master), the source from which all copies will be produced (via methods such as pressing, duplication or replication).
Magnetic-tape tape recorders record sound by magnetizing particles of ferromagnetic material, typically iron oxide (rust), coated on thin ribbons of plastic tape (or, originally, fragile paper tape). The tape coating is magnetized by dragging it over the surface of a small recording head (typically the size of a sugar cube) which contains an ...
Magnetic tape also brought about a radical reshaping of the recording process—it made possible recordings of far longer duration and much higher fidelity than ever before, and it offered recording engineers the same exceptional plasticity that film gave to cinema editors—sounds captured on tape could now easily be manipulated sonically ...
The use of magnetic tape for sound recording can be traced back to 1924 when German engineer, Kurt Stille, developed a dictation machine that used steel wires called the Poulsen wire recorder. [1] Louis Blattner , a German engineer working in Britain, licensed Stille's technology the following year and started work on a machine that would be ...
A magnetisation distribution is achieved along the magnetic tape. Finally, the distribution of the magnetisation can be read out, reproducing the original signal. The magnetic tape is typically made by embedding magnetic particles (approximately 0.5 micrometers [4] in size) in a plastic binder on polyester film tape. The most commonly-used of ...
