Magnetic tape is a medium for magnetic recording, made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on magnetic wire recording. Devices that record and playback audio and video using magnetic tape are tape recorders and video tape recorders respectively. A device that stores computer data on magnetic tape is known as a tape drive.
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. It was developed by the Dutch company Royal Philips in Hasselt, Belgium, by Lou Ottens and his team. It was introduced in September 1963. Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (Musicassette), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user.
Digital Audio Tape is a signal recording and playback medium developed by Sony and introduced in 1987. In appearance it is similar to a Compact Cassette, using 3.81 mm / 0.15" magnetic tape enclosed in a protective shell, but is roughly half the size at 73 mm × 54 mm × 10.5 mm. The recording is digital rather than analog. DAT can record at sampling rates equal to, as well as higher and lower than a CD at 16 bits quantization. If a comparable digital source is copied without returning to the analogue domain, then the DAT will produce an exact clone, unlike other digital media such as Digital Compact Cassette or non-Hi-MD MiniDisc, both of which use a lossy data reduction system.
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. In its present-day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal. Tape-recording devices include the reel-to-reel tape deck and the cassette deck, which uses a cassette for storage.
Analog recording is a technique used for the recording of analog signals which, among many possibilities, allows analog audio for later playback.
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 source from which all copies will be produced. In recent years digital masters have become usual, although analog masters—such as audio tapes—are still being used by the manufacturing industry, particularly by a few engineers who specialize in analog mastering.
Reel-to-reel audio tape recording, also called open-reel recording, is the form of magnetic tape audio recording in which the recording medium is held on a reel that is not permanently mounted in an enclosed cassette. In use, the supply reel containing the tape is placed on a spindle or hub; the end of the tape is manually pulled out of the reel, threaded through mechanical guides and a tape head assembly, and attached by friction to the hub of the second, initially empty takeup reel.
Monaural or monophonic sound reproduction is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or stereo, which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of the direction of sound sources. In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical signals are fed to each speaker, resulting in the perception of one-channel sound "imaging" in one sonic space between the speakers. Monaural recordings, like stereo ones, typically use multiple microphones fed into multiple channels on a recording console, but each channel is "panned" to the center. In the final stage, the various center-panned signal paths are usually mixed down to two identical tracks, which, because they are identical, are perceived upon playback as representing a single unified signal at a single place in the soundstage. In some cases, multitrack sources are mixed to a one-track tape, thus becoming one signal. In the mastering stage, particularly in the days of mono records, the one- or two-track mono master tape was then transferred to a one-track lathe intended to be used in the pressing of a monophonic record. Today, however, monaural recordings are usually mastered to be played on stereo and multi-track formats, yet retain their center-panned mono soundstage characteristics.
Ripping is extracting all or parts of digital contents from a container. Originally, it meant to rip music out of Amiga games. Later, the term was used to extract WAV or MP3 format files from digital audio CDs, but got applied as well to extract the contents of any media, most notably DVD and Blu-ray discs.
An album is a collection of audio recordings issued as a collection on compact disc (CD), vinyl, audio tape, or another medium. Albums of recorded sound were developed in the early 20th century as individual 78-rpm records collected in a bound book resembling a photograph album; this format evolved after 1948 into single vinyl LP records played at 33+1⁄3 rpm.
The Audio Home Recording Act of 1992 (AHRA) amended the United States copyright law by adding Chapter 10, "Digital Audio Recording Devices and Media". The act enabled the release of recordable digital formats such as Sony and Philips' Digital Audio Tape without fear of contributory infringement lawsuits.
Sound recording and reproduction is an electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording.
In copyright law, a mechanical license is a license from the holder of a copyright of a composition or musical work, to another party to "cover song", reproduce, or sample a portion of the original composition. It applies to copyrighted work that is neither a free/open source item nor in the public domain.
The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods:
The Section 115 Reform Act of 2006 was a bill introduced June 8, 2006 in the 109th United States Congress by Howard Berman (California-D) and Lamar Smith (Texas-R) as part of. It is one of several recent attempts to modify Section 115 of the United States Copyright Act to accommodate digital delivery of musical works.
The sound recording copyright symbol or phonogram symbol, represented by the graphic symbol ℗, is the copyright symbol used to provide notice of copyright in a sound recording (phonogram) embodied in a phonorecord. It was first introduced in the Rome Convention for the Protection of Performers, Producers of Phonograms and Broadcasting Organisations. The United States added it to its copyright law as part of its adherence to the Geneva Phonograms Convention. Its use is currently set out in 17 U.S.C. § 402, the codification of the Copyright Act of 1976.
In United States copyright law, a copyright notice is a notice of statutorily prescribed form that informs users of the underlying claim to copyright ownership in a published work.
The LP is an analog sound storage medium, a phonograph record format characterized by: a speed of 33+1⁄3 rpm; a 12- or 10-inch diameter; use of the "microgroove" groove specification; and a vinyl composition disk. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it remained the standard format for record albums until its gradual replacement from the 1980s to the early 2000s, first by cassettes, then by compact discs, and then by music downloads and streaming. The LP has experienced a revival in popularity since about 2007.
A videocassette recorder (VCR) or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other source on a removable, magnetic tape videocassette, and can play back the recording. Use of a VCR to record a television program to play back at a more convenient time is commonly referred to as timeshifting. VCRs can also play back prerecorded tapes. In the 1980s and 1990s, prerecorded videotapes were widely available for purchase and rental, and blank tapes were sold to make recordings.
Fixation in Canadian copyright law is a threshold consideration that must be used in copyright infringement cases by courts to determine if copyright actually exists.
