Highway Hi-Fi was a system of proprietary players and seven-inch phonograph records with standard LP center holes designed for use in automobiles. Designed and developed by Peter Goldmark, [1] who also developed the LP microgroove, the discs utilized 135 grams of vinyl each, enough to press a standard 10-inch LP (12-inch LPs of the period commonly used 160 grams of vinyl each and 45s used roughly 70 grams).
The system appeared in Chrysler automobiles from 1955 [2] to 1959 (1956–1959 model years). Records for the system were manufactured exclusively by Columbia Special Products, and could hold roughly 45 minutes of music or an hour of speech per side. This was accomplished by the use of a lower rotation speed of 16+2⁄3 rpm (versus 33+1⁄3 rpm for conventional long-playing records, and 45 rpm for singles) in conjunction with an extremely tight groove pitch of 550 grooves per inch (216.5 grooves per centimeter), over four times that of a standard monaural LP of the period, and an extremely small ultra-microgroove width of only 0.25 mils (6.4 μm), roughly one-third the groove width of a standard stereo LP, at 0.7 mils.
In the most extreme cases of spoken word where high fidelity near the center was not an issue, the recording surface extended to an unusually small diameter of 2+1⁄4 inches (57 mm), which constrained the label to 1+1⁄2 inches (38 mm) for long-playing titles. Demonstration discs and musical selections where high fidelity near the center was an issue were manufactured with standard 3-inch (76 mm) labels.[ citation needed ]
The players themselves were manufactured by CBS Electronics. According to the official Chrysler press release of September 12, 1955, "Highway Hi-Fi plays through the speaker of the car radio and uses the radio's amplifier system. The turntable for playing records, built for Chrysler by CBS-Columbia, is located in a shock-proof case mounted just below the center of the instrument panel. A tone arm, including sapphire stylus and ceramic pick up, plus storage space for six long-play records make up the unit." A button controlled whether you listened to the radio or the records. [3] A proprietary 0.25-mil (i.e., 0.00025 in or 6.4 μm or a quarter of a "thou") stylus was used with an unusually low stylus pressure of 2 grams-force (20 mN; 0.071 ozf) to allow for long stylus life. [4]
Highway Hi-Fi units were factory-installed and were not available as aftermarket add-ons. With a tendency to break or malfunction, and a limited number of titles (which were available solely from one label's back catalog), the product was not a commercial success; Chrysler slowly began to pull support for Highway Hi-Fi as early as 1957 when high warranty service costs became evident. Another automobile record player was manufactured by RCA from 1960 to 1961. This later version dropped the "Highway Hi-Fi" label (not being Chrysler-exclusive) and played standard 45-rpm 7-inch (180 mm) records. [5] It, too, suffered a short lifespan: the players were even more prone to malfunction than those manufactured by CBS, and standard 7-inch records had their grooves worn down rapidly by the high stylus pressure used to prevent skipping.
In music, a single is a type of release of a song recording of fewer tracks than an album or LP record, typically one or two tracks. A single can be released for sale to the public in a variety of physical or digital formats. Singles may be standalone tracks or connected to an artist's album, and in the latter case would often have at least one single release before the album itself, called lead singles.
A phonograph record, a vinyl record, or simply a record or vinyl is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph.
Pathé Records was an international record company and label and producer of phonographs, based in France, and active from the 1890s through the 1930s.
The twelve-inch single is a type of vinyl gramophone record that has wider groove spacing and shorter playing time with a "single" or a few related sound tracks on each surface, compared to LPs which have several songs on each side. It is named for its 12-inch (300 mm) diameter. This allows for louder levels to be cut on the disc by the mastering engineer, which in turn gives a wider dynamic range, and thus better sound quality. This record type is commonly used in disco and dance music genres, where DJs use them to play in clubs. They are played at either 33+1⁄3 or 45 rpm. The conventional 7-inch single usually holds three or four minutes of music at full volume. The 12-inch LP sacrifices volume for extended playing time.
The Edison Diamond Disc Record is a type of phonograph record marketed by Thomas A. Edison, Inc. on their Edison Record label from 1912 to 1929. They were named Diamond Discs because the matching Edison Disc Phonograph was fitted with a permanent conical diamond stylus for playing them. Diamond Discs were incompatible with lateral-groove disc record players, e.g. the Victor Victrola, the disposable steel needles of which would damage them while extracting hardly any sound. Uniquely, they are just under 1⁄4 in thick.
A magnetic cartridge, more commonly called a phonograph cartridge or phono cartridge or (colloquially) a pickup, is an electromechanical transducer that is used to play phonograph records on a turntable.
A format war is a competition between similar but mutually incompatible technical standards that compete for the same market, such as for data storage devices and recording formats for electronic media. It is often characterized by political and financial influence on content publishers by the developers of the technologies. Developing companies may be characterized as engaging in a format war if they actively oppose or avoid interoperable open-industry technical standards in favor of their own.
The Capacitance Electronic Disc (CED) is an analog video disc playback system developed by Radio Corporation of America (RCA), in which video and audio could be played back on a TV set using a special stylus and high-density groove system similar to phonograph records.
The overwhelming majority of records manufactured have been of certain sizes, playback speeds, and appearance. However, since the commercial adoption of the gramophone record, a wide variety of records have also been produced that do not fall into these categories, and they have served a variety of purposes.
The Chrysler B and RB engines are a series of big-block V8 gasoline engines introduced in 1958 to replace the Chrysler FirePower engines. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi" due to their hemispherical shaped combustion chambers. The corporation had been seeking a smaller and lighter replacement for its FirePower engines, in part because new styling dictates meant moving the engine forward in the chassis which negatively affected weight distribution.
The Muntz Stereo-Pak, commonly known as the 4-track cartridge, is a magnetic tape sound recording cartridge technology.
Peter Carl Goldmark was a Hungarian-American engineer who, during his time with Columbia Records, was instrumental in developing the long-playing microgroove 331⁄3 rpm phonograph disc, the standard for incorporating multiple or lengthy recorded works on a single disc for two generations. The LP was introduced by Columbia's Goddard Lieberson in 1948. Lieberson was later president of Columbia Records from 1956–1971 and 1973–1975. According to György Marx, Goldmark was one of The Martians.
RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA). The purposes of the equalization are to permit greater recording times, to improve sound quality, and to reduce the groove damage that would otherwise arise during playback.
The DeSoto Adventurer is a full-sized automobile that was produced by DeSoto from 1956 through the 1961 model year. Introduced as a four-seat high-performance sports coupe concept car, the Adventurer ended up being DeSoto's special, limited-production, high-performance model, similar to the more luxurious and exclusive "letter series" Chrysler 300 and Chrysler Saratoga.
Stanton Magnetics, doing business as Stanton, is a business unit of inMusic Brands that designs and markets turntables, cartridges, DJ mixers, DJ media players, and DJ controllers.
The LP is an analog sound storage medium, specifically 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 Records in 1948, it was soon adopted as a new standard by the entire US record industry and, apart from a few relatively minor refinements and the important later addition of stereophonic sound in 1957, it remained the standard format for record albums during a period in popular music known as the album era. LP was originally a trademark of Columbia and competed against the smaller 7-inch sized "45" or "single" format by RCA Victor, eventually ending up on top. Today in the vinyl revival era, a large majority of records are based on the LP format and hence the LP name continues to be in use today to refer to new records.
Direct metal mastering (DMM) is an analog audio disc mastering technique jointly developed by two German companies, Telefunken-Decca (Teldec) and Georg Neumann GmbH, toward the end of the 20th century after having seen the same technology used by RCA Princeton Labs for its SelectaVision videodiscs in the late 1970s.
In the production of phonograph records – discs that were commonly made of shellac, and later, vinyl – sound was recorded directly onto a master disc at the recording studio. From about 1950 on it became usual to have the performance first recorded on audio tape, which could then be processed and/or edited, and then dubbed on to the master disc.
The Seeburg 1000 Background Music System is a phonograph designed and built by the Seeburg Corporation to play background music from special 162⁄3 RPM vinyl records in offices, restaurants, retail businesses, factories and similar locations. Seeburg provided a service similar to that of Muzak.
Electrical transcriptions are special phonograph recordings made exclusively for radio broadcasting, 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.
