Levykokoina

Levykokoina, also known as vinyl records, are analog audio recordings on discs made from a flexible material, usually polyvinyl chloride (PVC). They were developed in the late 19th century and became popular in the mid-20th century, particularly during the 1950s and 1960s. Vinyl records are known for their high audio quality and durability, as they are less susceptible to degradation over time compared to other formats like cassette tapes.

The process of creating a vinyl record involves several steps. First, the audio signal is recorded onto a master disc using a lathe. This master is then used to create a stamper, which is a metal disc with the audio grooves pressed into it. The stamper is then used to press the final vinyl records, which are made from a PVC base with a protective lacquer coating.

Vinyl records come in various sizes, with the most common being 12 inches (30 cm) in diameter. They can store either analog audio or digital audio, and can be played on a turntable with a stylus that reads the grooves. Vinyl records are often collected for their aesthetic value, as well as their musical content, and are a popular format for vinyl enthusiasts and music collectors.

In recent years, there has been a resurgence in vinyl record sales, driven by a renewed interest in high-fidelity audio and a desire for tangible, physical music. This has led to an increase in the production and availability of vinyl records, as well as a growth in the number of independent record labels and vinyl-only stores. Despite the rise of digital music, vinyl records remain a popular and enduring format for music lovers around the world.
