A phonograph report (also known as a gramophone file, in particular in British English), or really a record, is an analog sound storage medium inside the shape of a flat disc with an inscribed, modulated spiral groove. The groove generally starts near the periphery and ends close to the center of the disc. At first, the discs had been commonly made from shellac, with earlier information having a satisfactory abrasive filler jumbled in. Starting inside the Forties polyvinyl chloride became common, subsequently the call “vinyl”.

The phonograph document was the primary medium used for track replica during the twentieth century. It had co-existed with the phonograph cylinder from the late Eighteen Eighties and had successfully superseded it with the aid of round 1912. Records retained the biggest marketplace percentage even when new codecs including the compact cassette were mass-advertised. By the 1980s, digital media, within the form of the compact disc, had won a bigger marketplace percentage, and the document left the mainstream in 1991.[1] Since the 1990s, facts stay synthetic and sold on a smaller scale, and at some stage in the Nineteen Nineties and early 2000s had been generally utilized by disc jockeys (DJs), particularly in dance music genres. They were also listened to with the aid of a developing range of audiophiles. The phonograph document has made a gap resurgence as a layout for rock song within the early twenty first century—9.2 million records were sold within the US in 2014, a 260% growth on the grounds that 2009.[2] Likewise, income within the UK improved 5-fold from 2009 to 2014.[three]

As of 2017, 48 report pressing centers exist global, 18 in the US and 30 in different countries. The accelerated reputation of the document has led to the funding in new and modern-day report-pressing machines.[four] Only manufacturers of lacquers (acetate discs or master discs) stay: Apollo Masters in California, and MDC in Japan.[five] On 6 February 2020, a hearth destroyed the Apollo Masters plant. According to the Apollo Masters website, their future continues to be unsure.[6]

Phonograph records are generally described by using their diameter in inches (12-inch, 10-inch, 7-inch) (although they had been designed in millimeters[7]), the rotational speed in revolutions per minute (rpm) at which they’re played (8+1⁄three, sixteen+2⁄three, 33+1⁄3, 45, 78),[eight] and their time capacity, decided with the aid of their diameter and pace (LP [long gambling], 12-inch disc, 33+1⁄three rpm; SP [unmarried], 10-inch disc, seventy eight rpm, or 7-inch disc, forty five rpm; EP [prolonged play], 12-inch disc or 7-inch disc, 33+1⁄three or forty five rpm); their reproductive exceptional, or stage of fidelity (high-constancy, orthophonic, full-variety, and many others.); and the range of audio channels (mono, stereo, quad, and many others.).

The word broken report refers to a malfunction[nine] when the needle skips/jumps returned to the previous groove and performs the same phase over and over once more indefinitely.[10][11][12]History[edit]Predecessors[edit]

The phonautograph was invented on 25 March 1857 by means of Frenchman Édouard-Léon Scott de Martinville,[thirteen] an editor and typographer of manuscripts at a scientific publishing house in Paris.[14] One day at the same time as enhancing Professor Longet’s Traité de Physiologie, he came about upon that patron’s engraved illustration of the anatomy of the human ear, and conceived of “the imprudent concept of photographing the phrase.” In 1853 or 1854 (Scott mentioned each years) he began working on “le problème de l. a. parole s’écrivant elle-même” (“the hassle of speech writing itself”), aiming to construct a device that might reflect the function of the human ear.[14][15]

Scott coated a plate of glass with a thin layer of lampblack. He then took an acoustic trumpet, and at its tapered give up affixed a thin membrane that served because the analog to the eardrum. At the center of that membrane, he connected a inflexible boar’s bristle about a centimeter lengthy, located so that it simply grazed the lampblack. As the glass plate became slid horizontally in a nicely shaped groove at a velocity of one meter in keeping with second, someone could talk into the trumpet, causing the membrane to vibrate and the stylus to hint figures[14] that were scratched into the lampblack.[16] On 25 March 1857, Scott acquired the French patent[17] #17,897/31,470 for his tool, which he called a phonautograph.[18] The earliest recognized surviving recorded sound of a human voice turned into carried out on nine April 1860 when Scott recorded[sixteen] someone making a song the track “Au Clair de la Lune” (“By the Light of the Moon”) on the device.[19] However, the device turned into not designed to play returned sounds,[sixteen] as Scott intended for people to study back the tracings,[20] which he known as phonautograms. By overdue 1857, with aid from the Société d’encouragement pour l’industrie nationale, Scott’s phonautograph became recording sounds with enough precision to be followed with the aid of the clinical network, paving the manner for the nascent technological know-how of acoustics.[15]

The tool’s actual importance inside the history of recorded sound was now not completely found out prior to March 2008, whilst it turned into determined and resurrected in a Paris patent office by way of First Sounds, an informal collaborative of American audio historians, recording engineers, and sound archivists based to make the earliest sound recordings to be had to the public. The phonautograms were then digitally converted through scientists on the Lawrence Berkeley National Laboratory in California, who had been able to play returned the recorded sounds, something Scott had never conceived of. Prior thus far, the earliest recognised report of a human voice became concept to be an 1877 phonograph recording by using Thomas Edison.[16][21] The phonautograph could play a position in the improvement of the gramophone, whose inventor, Emile Berliner, worked with the phonautograph in the route of growing his very own tool.[22]

Edison invented the phonograph in 1877. Unlike the phonautograph, Edison’s phonograph may want to each report and reproduce sound.Edison first tried recording sound on a wax-impregnated paper tape, with the concept of creating a “smartphone repeater” analogous to the telegraph repeater he were running on. Although the seen outcomes made him assured that sound may be physically recorded and reproduced, his notes do now not suggest that he absolutely reproduced sound earlier than his first test wherein he used tinfoil as a recording medium numerous months later. The tinfoil turned into wrapped round a grooved steel cylinder and a legitimate-vibrated stylus indented the tinfoil at the same time as the cylinder was turned around. The recording might be played lower back right now. The Scientific American article that brought the tinfoil phonograph to the public mentioned Marey, Rosapelly and Barlow, in addition to Scott as creators of devices for recording however, importantly, not reproducing sound.[23]

In 1910, Edison found out that cylinders had peaked, and finally embraced discs with the creation of the Edison Disc Phonograph.[24]Lateral-cut discs[edit]

In August 1900, after a quick duration working in Philadelphia for the Berliner Gramophone Co., which became closed through a felony action, Leon Douglass agreed[25] to enter enterprise with Eldridge R. Johnson, who owned a device keep in Camden, New Jersey and had supplied machines to Berliner. The enterprise commenced doing business in September 1900 as The Consolidated Talking Machine Company however modified to using Johnson’s call due to a conflict with a Berliner organisation call.On three October 1901 it integrated as the Victor Talking Machine Company.[citation wanted][26]

Emile Berliner stepped forward the great of recordings at the same time as his manufacturing companion Eldridge R. Johnson subsequently progressed the mechanism of the gramophone with a spring motor and a velocity regulating governor, resulting in a valid pleasant same to Edison’s cylinders. Abandoning Berliner’s “Gramophone” trademark for legal motives in the United States, in 1901 Johnson’s and Berliner’s separate businesses reorganized to shape the Victor Talking Machine Company in Camden, New Jersey, whose merchandise would come to dominate the marketplace for decades.[27]

The manufacturing unit, which have become the Canadian branch of RCA Victor, still exists. There is a devoted museum in Montreal for Berliner (Musée des ondes Emile Berliner).[28]78 rpm disc traits[edit]

Hungarian Pathé file, 90 to one hundred rpmEarly speeds[edit]

Early disc recordings were produced in loads of speeds ranging from 60 to one hundred thirty rpm, and a lot of sizes. As early as 1894, Emile Berliner’s United States Gramophone Company changed into promoting single-sided 7-inch discs with an marketed wellknown speed of “approximately 70 rpm”.[29]

One trendy audio recording handbook describes pace regulators, or governors, as being part of a wave of development introduced unexpectedly after 1897. A image of a hand-cranked 1898 Berliner Gramophone indicates a governor, and says that spring drives had replaced hand drives. It notes that:
