Laquer was too hard to use in actual manufacturing, so a metal casting pattern was made. Initially, the laquer was covered with a layer of good conductive graphite, then silver or nickel plated. Once the plate is thick enough, the wax will be removed, leaving behind a stronger metal mold.

Modern techniques require immersing the disc in a solution of stannous chloride and then spraying it on a layer of silver atoms. Plating plates with conventional techniques are still widely used but do not achieve accurate reverberation.

After the initial silver plating has hardened, a fine copper layer is applied, followed by a stronger, coarser layer of metal, such as steel. Fine metal layer, composed of relatively small metal atoms, 85 particles/inch2 with magnification of 100 times the diameter, and features improved strength and toughness than rough steel particles, easily machined more work on the machine.

When the amount of metal was sufficient to support the silver plates, the laquer was smashed into the mold, leaving a metal cathode, or “mortar”.

The mold is still quite hard so it needs to be cast again before starting to compress the vinyl. The metal dish is referred to as the “mother”, cut from a mortar and then plated again to create another sound called a “stamper.”

Each stamper is attached to a 100 ton hydraulic compressor, basically like a mold and can produce thousands of disks before needing replacement.

Each hot vinyl foil is only about half the area but 3 times thicker than a finished disc, called a biscuit, slides between the two compressor jaws, and 300oF steam is used to soften the material before finishing, and compress Hot vinyl on the final shape while recording. Then the disc is cooled with water, becomes hard, and is labeled, all of which are done automatically.

Next, the discs are angled in a neat circle with an automatic trimmer, after which the discs are carefully checked, both visually and acoustically.

Finally, quality LPs are packed and shipped to independent local music retail stores.

Above is the full progress of making vinyl discs, which are used for vinyl record. As can be seen, it is complicated to create vinyl discs that have such steady production levels and amazingly natural sound quality. Hope you know understand how vinyl discs are made.

The first idea about vinyl discs came about 140 years ago thanks to Edison’s phonograph design, and the first records were also made for the first time in 1948 thanks to Columbia with the first 12-inch coal disc in the world.

It was first introduced to the public on June 20, 1948 at Waldorf-Astoria Hotel, New York. And since then many new technologies and mechanisms for listening to music have been born, but removing the vinyl disc from the condom, gently putting it on the turntable and lowering the lever is still possible. Intense shot with most music lovers.

“This is the time for serious music appreciation to create great music performances by the means of record discs. It can be said that the record discs succeeded in accurately and fully reproducing all the details of the symphony or opera performance.

Electrical recording and reproduction have combined to maintain the vitality and color of solo performances. ”- Per Compton Pakenham of The New York Times in 1930.

And the quality only improved in the 1950s with the launch of 33 RPMs, at about 25 minutes each, and the sound strip could be easily edited and optimized for audio in production, then inserted into a master-disc. This master-disc is known as a laquer or acetate disc. In fact, acetate is a misnomer when laquer disks are covered with cellulose nitrate.

And unlike most vinyl discs that are molded, master-discs are cut “manually”, grooves on the surface of the disc are created using a disc cutter needle with mechanical movements controlled by an audio input.

The grooves are checked regularly during the cutting process to ensure the proper depth of the cut path as well as adjust the volume and pitch. After the audio has been copied and the playback quality checked, the laquer will be sent to the production company.

While the digital world is thriving, vinyl LPs continue to be collected along with steady production levels, perhaps due to their warm, natural analog sound quality. So, how can LP achieve such unique sound effects!

In 1877, Thomas Edison was credited with inventing the phonograph, the first device to both record and play back sound.

The device records sound directly when dents on the foil wrap around a grooved roller, which is then played back by rotating the roller, following the needle tip movement along the lines. The groove, vibrates the corresponding mechanical diaphragm and reproduces sound.

By the 1880s, Volta invented a wax-coated cardboard cylinder using the vibration of a phonograph needle, like a seismometer, called the “hill-and-dale” method, like that of Edison.

It was not until the early 20th century that the cylinder was eventually replaced by the flat disc records we use today. But even then, the sound was recorded directly to the disk mechanically.

“Acoustical” records like this rely on a large audio device connected to a gramophone needle. When the sound waves cause vibrations, it will cause the needle to vibrate, and put those vibrations into the hand-cranked disc.

The problem is that the amplitude of the bass notes (bass notes) is many times higher than the notes with the higher tonal range, the sound with the lower pitch takes more physical distance in each segment, then, high and mid tones will be lost during playback. This causes distorted pronunciation as well as heavy bass.

It was not until 1925 that audio inputs were run through a microchip and amp to increase the operating range and volume without depending on the physical properties of the audio equipment, and the era of the “electrical” records have begun.

These recordings are intentionally tuned to the highs and low lows, helping to balance the sound during playback. 78s – discs with a rotating speed of 78 RPM – are considered a technological leap compared to their predecessors.

Vinyl record recording – reading techniques are analog that brings the high fidelity to the sound, and the players call it “rustic sound”. The sound of vinyl record has its own distinct characteristics that are different from digital. When listening to a good type of vinyl record player, the sound was floating, the position of the instruments playing in the orchestra appeared very clearly, the singer’s voice was sweet and inspiring. For this reason, there are still many people in the world who are passionate about collecting and enjoying vinyl record. Especially those who love classical music, Jazz – Blue and acoustic instruments…

The vinyl record’s attractive secret

The first vinyl record was born about hundred years but still caught interests by music players, despite the advent of a series of new technologies. Unique beauty with “rustic” sound is the attractive secret of vinyl record.

First record invented by Thomas Edison

1877 Thomas A. Edison – the American genius inventor who invented the first tape recorder, which works on the basis of sound waves delivered through a transducer to create the markings from a needle on a metal cylinder. When reproduce the sound, the needle is read from the recorded metal tube, the mechanical oscillation of the needle is through a mechanical amplification system to raise the amplitude and then speak out through loudspeaker. Although the band is still very narrow and distorted, Edison’s recorder has laid the first foundation for sound reproduction and processing technology.

Companies adapted Edison’s principle

Adapted from Edison’s recording principle, right from the end of the nineteenth century and the early twentieth century, a number of firms in the world have released mechanical recorders that are powered by cords with a bright golden copper speaker which as big as a tuba. This phonograph has been regarded as a luxury decoration among wealthy families in Europe earlier in the century.

The phonograph invented and improved

Vinyl record production is not much different from Edison’s original recording principle. In 1887,  Emile Berliner (USA) invented the first phonograph. To improve sound quality, industrial-scale sound recording technology has been constantly improved. There is a significant step forward from the first recordings with 78-minute mono recording techniques to a hi-fi long playing 33 rpm vinyl record. In the field of disc manufacturing, the names of record labels with many major contributions include: RCAVictor, EMI (USA), Decca Record (UK), Deuts Gramophon (Germany) …

 

 

 

 

 

 

 

 

 

Cassettes and coal discs are pulling together back to the music market, where they seem to have been shelved since the booming digital era.

The small, rectangular plastic cassette contains all the good things of many generations back, along with vinyl charcoal.

Some of today’s top musicians, including Ariana Grande and Justin Bieber, have released personal music albums on cassettes. It seems that they will not be welcome but in fact their albums sell as quick as hot cakes and demand continues to increase.

According to Guardian, sales of cassettes increased by 125% in 2018. That same year, 50,000 cassette albums were sold in the UK, the highest number in the last 15 years.

Obviously that number is nothing compared to 1989, there are 83 million albums of cassettes sold in the UK. But the number of 50,000 copies is marking the revival of an old-fashioned form of music enjoyment. Why so?

Timeless values

“Music is not just about listening online or downloading, listening to music must be interesting. Cassette is very interesting. Unlike electronic music, music on cassettes has a short lifespan, which makes us appreciate them and suffer when lost “- DJ Phin, who just released the album on the cassette, said.

American clothing brand Urban Outfitters describes: “You have to experience the feeling of waiting for three or four hours on the radio to listen to your favorite music and then record it into a cassette tape, you know just how interesting it is. “.

Many people believe that few people listen to music on cassettes today, buying tapes is seen as a collection.

Thanks to the warm welcome of audiences, cassette tapes bring a big income to artists. According to Guardian, Ariana Grande’s Thank U and Next song topped the ranking sold on cassettes (540 copies sold last week). Musicians like AC / DC, Kylie Minogue or Jade Bird also raced to release a cassette album.

Along with the development of technology, services like Sportify or Apple Music are increasingly dominating the music market and creating convenience for audiophiles when they simply need to download songs to the computer.

However, in 2018, sales of music download services were unexpectedly lower than CDs and vinyl record – those that sounded like obsolete music.

Many people buy CDs and vinyl record

According to the Recording Association of America (RIAA), the total number of downloads on music services – with iTunes at the top, has dropped by approximately 30% in 2018, to just over 1 billion USD. Besides, the revenue from downloading albums also decreased by 25%.

Meanwhile, sales of seemingly “extinct” vehicles such as CDs, vinyls record reported by the RIAA, still maintain the figure of $ 1.15 billion, thereby officially surpassing the Electronic music service. Particularly, sales from coal discs, according to RIAA, amounted to 420 million USD.

Another comparison shows the decline in digital music services, which have accounted for 40% of the audio industry’s revenue in 2013. However, last year, this number only fell. at approximately 11%.

Stream service still dominates


Even so, both types of music are on the decline, and replaced by streaming services.

Even the sales of CDs and vinyl record are higher than music downloads, but still reduce more than 23% compared to the same period last year. In particular, sales from CDs alone decreased by 34%, to only 698 million USD. This is the first time sales from CDs have been less than $ 1 billion, since 1986.

On the other hand, revenue from stream services grew steadily by 30% last year, reaching US $ 7.4 billion, accounting for 75% of the industry’s revenue in 2018.

Also last year, the number of subscribers to streaming music on online services increased by 42% compared to 2017, and for the first time reached 50 million. The success of the music model also made Apple gradually convert its entire iTunes platform.

Listening to a vinyl record has been a very sophisticated listening style. People who come to this form of music are usually very delicate.

The sound of vinyl record is very different from the popular digital audio now. While the digital sound is somewhat magical, it is easy to adjust the sound, the pitch of the singer, the sound of the vinyl record has its own charm. When listening to a good performance of a vinyl record, people hear stereo sound, as if you are listening to live orchestra playing, the position of the instruments in the orchestra, the vocalist’s real and inspiring voice. Therefore, in the world in general, there is still a difficult part of listeners, especially love, collect and enjoy vinyl record. Special music that fit vinyl record like Jazz – Blue, classical music or Acoustic instruments.

The vinyl record has a three-piece structure: the reader or phonocatridge, the mechanical part or the tonearm, the turntable part is the rotary wheel and the motor. There are two types of common readers: “dynamic magnet” or MM needle (Moving Magnet). The second type is called “Dynamic Coil” or MC needle (Moving Coil). The cheaper MM is very popular, the MC gives better sound quality than the MM type, most expensive readers are now MC types.

Perhaps the vinyl record player, besides enjoying the sound of it, also requires the character of the person to be careful, sophisticated and must have ears for music. For vinyl record players, besides the main investment is buying gramophone, sound, speaker, vinyl record … players also have to invest in spare parts such as compressed air dust guns, carbon brushes to sweep dust on coal plates. (For example, an $ 15 AudioQuest brush), antistatic spray (such as $ 50 Allsop Orbitrac 2 disk cleaner), special brush and solution to clean the needle tip of the record. Coal discs must be stored carefully in a glass cabinet to avoid dust, environmental humidity or high temperatures, causing the disc to explode or warp

5. Location Set Turntable

You need an overall observation to arrange turntable so that it is most reasonable. This may not sound like a big deal, but this work contributes to a more viable effect instead of simply placing the turntable on the shelf.

On the other hand, vibration is a visible phenomenon when turntable is active. In theory, vibration occurs when the needle moves through the grooves in the record and produces sound. The vibrations from the outside, therefore, will also blend into the signal, usually hiding in the form of noise. If the vibration exceeds the permissible level, it will cause the “needle to jump” and everything becomes a disaster. Therefore, music lovers need to put the turntable on a solid surface to eliminate generated noise, such as a coal disk shelf designed specifically for effective vibration reduction.

6. How To Upgrade The Components?

Regular system upgrades depend on the cost of the player. Accordingly, with the introductory models (entry-level), allow audiophiles to replace or adjust some components as follows:

The Platter
Platter is the part used to place the record directly. Considering the general principle, the heavier the platter opens up the vibration resistance better. Therefore, vinyl lovers can use Platter to improve vibration resistance.

Tonearm

Tonearm is a suspension device that exposes the disc of the disc to contact the vinyl surface. The quality of the disc needs to significantly affect the accuracy and stability of the rotating disc.

Stylus

Stylus functions to interact with grooves on LP, as well as bridging to reproduce realistic and detailed sound. Updating slylus is easy, done quite often by users.

Finally, music lovers need to consider choosing to buy a fully analog signal processor player in combination with an analog to digial converter or a built-in USB turntable to “digitize” vinyl music sources.
