How are vinyl records made?

An engineer cuts the groove in real time on a lathe into a lacquer, an aluminum disc with a lacquer coat, one per side. The lacquer is silvered and electroplated with nickel to make metal parts, ending in stampers. A warm lump of PVC is then squeezed between two stampers in a press, on the order of 100 tons for about half a minute.

Why is vinyl so expensive?

Setup costs land on every run whatever its size, so small runs cost far more per record: one US plant's 2026 card lists $11.69 a record at 100 copies and $3.35 at 1,000. Once the record is in a shop, one label's breakdown of a $24 LP gave about 35% to the retailer and 25% to the manufacturer. A plant owner told GRAMMY.com in 2022 that the price of PVC had increased three times since the plant opened in 2020.

What do 33, 45 and 78 mean on a record?

They are speeds in revolutions per minute. The 33 1/3 rpm LP came from Columbia in 1948 and became the album, and RCA Victor's 7-inch 45 rpm record of 1949 became the single. The 78 is the older shellac format, made commercially from 1897 until the late 1950s.

What do the etchings in the runout groove mean?

The smooth band by the label, the dead wax, carries a matrix number for each side plus cut numbers, stamper codes, plant marks and sometimes the cutting engineer's initials or signature. The codes exist so the factory can file stampers and match each side to the right label; collectors use them to tell pressings apart.

How can I tell if I have a first pressing?

No single mark proves it, because a first cut may have been rejected and reissues often restart at 1. Collectors stack evidence: the lowest cut and stamper numbers in the runout, the label design, jacket details, and the barcode test, since barcodes were not widely used before the late 1970s. Cross-check Discogs against forums and specialist sites, since Discogs has errors.

How should I store vinyl records?

Store them upright, on edge, with immovable dividers every 4 to 6 inches, and do not mix sizes on a shelf. The Library of Congress suggests room temperature or below and about 35 to 40% relative humidity at home, away from attics and basements. Keep them away from heat, which warps records, as a hot car shows.

Does vinyl sound better than digital?

The sources here do not settle it. A record has physical limits a digital file does not: longer sides cost level or bass, and the inner grooves near the label are harder to cut and track. A weight claim such as 180 grams says nothing about the quality of the cut or the pressing, and makers disagree on whether weight itself changes the sound.

Where are vinyl records pressed?

The largest presser, GZ Media near Prague in Czechia, pressed more than 55 million records in 2021 and runs plants in North America and France. In 2022 the North American trade body projected 43 plants in the US, nine in Canada and three in Mexico, and records are also pressed in Japan, Brazil, Germany and the Netherlands, among other countries.

Drop the needle Read your runout The whole album

A field guide to the vinyl record: how the sound gets cut into a lacquer, plated into metal and pressed into plastic, what all those sizes, speeds and colors change, what the scratched codes in the dead wax mean, how a turntable reads a groove, how DJs and collectors use records, what one costs and who gets paid, and where in the world they are made. Written for anyone, anywhere.

A record is a sound you can see. Hold one to the light and the loud passages look wider than the quiet ones, the gaps between songs are smooth bands, and the last half inch before the label carries handwriting: a catalog number, a letter, sometimes a joke, scratched there by the person who cut it.

It is also a format that should not have survived. In the US in 2025, vinyl brought in $1,042.9 million on 46.8 million units, against 29.5 million CDs, in what the RIAA counted as the 19th year of vinyl growth in a row.²⁴ In the UK, the BPI counted 7.6 million LPs sold in 2025, an 18th straight rise.²⁹

This guide explains how all of it works, start to finish: from the lathe that cuts the master, through the father, mother and stamper, to the steam press and the paper sleeve; then the needle, the DJ booth, the collector's grading sheet and the bill. It starts with a short history, and it comes with a decoder for the runout groove, so you can type in what is scratched in your own records and find out who made them.

Every factual claim is footnoted to the manufacturer, standard, filing, archive or reporting it came from, and every price and sales figure carries its year. Sentences without a footnote are our own explanation. Where a fact could not be pinned down, it is listed in the open questions at the end rather than guessed at. This guide is independent and not affiliated with any label, plant, store or brand named in it; cutting engineers, plant crews and collectors are welcome at the corrections desk.
