From Factory To Hi-Fi
You love your records. I'd almost bet they're precisely organized, their plastic sleeves free from any wrinkles. Collectors don't come much more serious than those who have fallen in love with vinyl albums. And whether your passion is rock vinyl, jazz vinyl or just about any genre under the sun, have you ever considered just how that perfect little piece of wax gets into your hands and on your turntable? It's a surprisingly simple process.
Logically, the method of producing and pressing the records of today has its roots in the steps first provided by Thomas Edison's photograph. But before anything resembling a vinyl record is produced, a medium is necessary. In the studio, a master recording is made, where musicians, producers and audio engineers work hand in hand to perfect the recorded sound.
A gloss is placed on a record-cutting machine once the master is attained. The varnish veneer dries to a perfectly smooth exterior during its production. As it rotates, electronic signals from the master recording are transmitted to a cutting head, which holds a stylus. An engineer moves the cutter and a microscope then looks at the test groove and adjustments are made to the cutter. Since the recording is one continuous groove, a computer monitors the cutting and adjusts the spacing between the grooves as needed. Although not a vinyl record yet, it's beginning to take shape.
From there, the imprinted lacquer is sent to a pressing plant - perhaps a more industrial-looking environment than most vinyl album enthusiasts would like to admit. The lacquer is then cleaned with soap and water and sprayed with liquid tin chloride and liquid silver. Making an inverse of the lacquer, as opposed to grooves, the ensuing metal master has ridges. The metal master is then used to produce a metal record, also known as the mother. A stamper is born from the mother. The stamper is put on a machine, which punches a hole in the middle and gets rid of the edges to create a diameter of 12 inches. Stampers are negative versions of the original recording that will be used to produce the actual vinyl albums.
Finally, the stamper is placed in a hydraulic press. Black Polyvinyl chloride pellets are placed in an extruder, which turns them into small "biscuits". The biscuit is then placed in the press which has two stampers encased within - one for each side of the record. Steam softens the plastic while the stampers create impressions of the master recording onto soon-to-be-vinyl albums. Then, cool water is utilized to harden the disc. The last step? Finding its place in your vinyl record collection and on your turntable, whether its rock vinyl or jazz vinyl.
