A Short History and Development of Vinyl Records

 

 

The history of vinyl records started in 1930, when RCA Victor launched the first commercially-available long playing vinyl record - marketed as "Program Transcription" discs. These revolutionary discs were designed for playback at 33 1/3 rpm and pressed on a 12" diameter flexible plastic disc.

 

In Roland Gelatt's book The Fabulous Phonograph, the author notes that RCA Victor's early introduction of a long-play disc was a commercial failure for several reasons including the lack of affordable, reliable consumer playback equipment and consumer wariness during the Great Depression.

 

However, vinyl's lower playback noise level than shellac was not forgotten. During and after World War II when shellac supplies were extremely limited, some 78 rpm records were pressed in vinyl instead of shellac (wax), particularly the six-minute 12" (30 cm) 78 rpm records produced by V-Disc for distribution to US troops in World War II.

 

Beginning in 1939, Columbia Records continued development of this technology. Dr. Peter Goldmark and his staff undertook exhaustive efforts to address problems of recording and playing back narrow grooves and developing an inexpensive, reliable consumer playback system. In 1948, the 12" (30 cm) Long Play (LP) 33 1/3 rpm microgroove record was introduced by the Columbia Record at a dramatic New York press conference.

 

The commercial rivalry between RCA Victor and Columbia Records led to RCA Victor's introduction of what it had intended to be a competing vinyl format, the 7" (17.5 cm) / 45 rpm Extended Play (EP). For a two-year period from 1948 to 1950, record companies and consumers faced uncertainty over which of these formats would ultimately prevail in what was known as the "War of the Speeds".

 

Eventually, the 12" (30 cm) / 33 1/3 rpm LP prevailed as the predominant format for musical albums, and the 7" (17.5 cm) / 45 rpm EP or "single" established a significant niche for shorter duration discs typically containing one song on each side. The EP discs typically emulated the playing time of the former 78 rpm discs, while the LP discs provided up to one-half hour of time per side.

 

After the introduction of high-quality but expensive stereo reel-to-reel tapes in 1955 and the increasing public fascination with stereo sound, intense work was undertaken to devise a scheme for recording stereo sound on 12" (30 cm) / 33 1/3 rpm LP. In late 1957, a system of cutting and playing back stereo was devised and generally accepted by the industry.

 

Consumer acceptance of stereo LPs was somewhat cautious initially but grew steadily during the early 1960s, and the industry largely discontinued production of conventional monaural LP records and playback equipment by 1968.

 

Eventually, the 12" (30 cm) / 33 1/3 rpm LP prevailed as the predominant format for musical albums, and the 7" (17.5 cm) / 45 rpm EP or "single" established a significant niche for shorter duration discs typically containing one song on each side. The EP discs typically emulated the playing time of the former 78 rpm discs, while the LP discs provided up to one-half hour of time per side.

 

Historically the most common formats are:

12" (30 cm) / 33 1/3 rpm LP 7" (17.5 cm) / 45 rpm EP or Single

followed by:

10" (25 cm)/ 45 rpm LP (superceeded by 12" (30 cm) / 33 1/3 rpm LP in the 60's) 12" (30 cm) / 33 or 45 rpm Maxi Single (introduced in the 80's)

Today most of the records are issued in 12" (30 cm) LP or Maxi Single.

 

The sound quality and durability of vinyl records is highly dependent on the quality of the vinyl used. Most vinyl records are pressed on recycled vinyl. New "virgin" or "heavy" (180-220 gram) is commonly used for classical music, although it has been used for some other genres.

 

Today, it is increasingly common in vinyl pressings that can be found in most record shops. Even modern albums like Shellac's and Mission of Burma's latest are pressed on 180 g/m² vinyl, though most are reissues of classic albums, like The Clash's series of reissues. These albums tend to withstand the deformation caused by normal play better than regular vinyl.

 

While most vinyl records are pressed from metal master discs, a technique known as lathe-cutting was introduced in the late 1980s by Peter King of Geraldine, New Zealand. A lathe is used to cut microgrooves into a clear polycarbonate disc.

 

Lathe cut records can be made inexpensively in small runs. However, the sound quality is significantly worse than proper vinyl records, and lathe cut records tend to degrade further in quality after repeated playing.
