Aluminum Disc
In the field of audio recording, an aluminum disc (aluminium in the UK and elsewhere) is a phonograph (gramophone in the UK) record made of bare aluminum, a medium introduced in the late 1920s for making one-off recordings. Although sometimes used for making amateur studio or home recordings or in coin-operated "record-your-voice" booths at fairs and arcades, during the first half of the 1930s bare aluminum discs were primarily used to record radio broadcasts for the private transcription disc archives of performers or sponsors.''Documenting Early Radio: A Review of Existing Pre-1932 Radio Recordings'' Elizabeth McLeod, 1988-9 In the record ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Old-time Radio
The Golden Age of Radio, also known as the old-time radio (OTR) era, was an era of radio in the United States where it was the dominant electronic home entertainment medium. It began with the birth of commercial radio broadcasting in the early 1920s and lasted through the 1950s, when television gradually superseded radio as the medium of choice for scripted programming, variety and dramatic shows. Radio was the first broadcast medium, and during this period people regularly tuned in to their favorite radio programs, and families gathered to listen to the home radio in the evening. According to a 1947 C. E. Hooper survey, 82 out of 100 Americans were found to be radio listeners. A variety of new entertainment formats and genres were created for the new medium, many of which later migrated to television: radio plays, mystery serials, soap operas, quiz shows, talent shows, daytime and evening variety hours, situation comedies, play-by-play sports, children's shows, cooking s ...

Transcription Disc
Electrical transcriptions are special phonograph recordings made exclusively for radio broadcasting,Browne, Ray B. and Browne, Pat, Eds. (2001). ''The Guide to United States Popular Culture''. The University of Wisconsin Press. . P. 263. which were widely used during the "Golden Age of Radio". They provided material—from station-identification jingles and commercials to full-length programs—for use by local stations, which were affiliates of one of the radio networks. Physically, electrical transcriptions look much like long-playing records that were popular for decades. They differ from consumer-oriented recordings, however, in that they were "distributed to radio stations for the purpose of broadcast, and not for sale to the public. The ET had higher quality audio than was available on consumer records"Hull, Geoffrey P. (2011). ''The Music and Recording Business: Delivering Music in the 21st Century''. Routledge. .

Surface Noise
In sound and music production, sonic artifact, or simply artifact, refers to sonic material that is accidental or unwanted, resulting from the editing or manipulation of a sound. Types Because there are always technical restrictions in the way a sound can be recorded (in the case of acoustic music, acoustic sounds) or designed (in the case of sound synthesis, synthesised or processed sounds), sonic errors often occur. These errors are termed artifacts (or sound/sonic artifacts), and may be pleasing or displeasing. A sonic artifact is sometimes a type of digital artifact, and in some cases is the result of data compression (not to be confused with dynamic range compression, which also may create sonic artifacts). Often an artifact is deliberately produced for creative reasons. For example to introduce a change in timbre of the original sound or to create a sense of cultural or stylistic context. A well-known example is the overdriving of an electric guitar or electric bass signal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyral
Pyral SAS is a manufacturer of magnetic recording media products, based in Avranches, France. As of 2015, it is a subsidiary of Mulann, a French company in the smartcard and ticketing industry. In 1934, Pyral created a new type of transcription disc. Their innovation was to coat the aluminum disc with a layer of lacquer. These discs came to be known as lacquers or acetates. As of 2007, The company's primary product is perforated magnetic tape, used to record sound for movie productions. They also produce magnetic inks and slurries used in the production of magnetic stripe cards.

Acetate Disc
An acetate disc (also known as a ''lacquer'', ''test acetate'', ''dubplate'', or ''transcription disc'') is a type of phonograph record generally used from the 1930s to the late 1950s for recording and broadcast purposes and still in limited use today. Acetate discs are used for the production of records. Unlike ordinary vinyl records, which are quickly formed from lumps of plastic by a mass-production molding process, an acetate disc is created by using a recording lathe to cut an audio-signal-modulated groove into the surface of a lacquer-coated blank disc, a sequential operation requiring expensive, delicate equipment and expert skill for good results. The disc is then coated in metal, which is then peeled off to form a negative that will later be electroplated and peeled to create a mother (positive copy) which is then again electroplated and peeled to create negatives called stampers, which are then used as molds in a record press. In addition to their use in the creation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrocellulose Lacquer
Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity. Asian lacquerware, which may be called "true lacquer", are objects coated with the treated, dyed and dried sap of ''Toxicodendron vernicifluum'' or related trees, applied in several coats to a base that is usually wood. This dries to a very hard and smooth surface layer which is durable, waterproof, and attractive in feel and look. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved, as well as dusted with gold and given other further decorative treatments. In modern techniques, lacquer means a range of clear or pigmented coatings that dry by solvent evaporation to produce a hard, durable finish. The finish can be of any sheen level from ultra matte to high gloss, and it can be further polished as required. Lacquer finishes ...

Hard Disk
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely on ...
