The response frequency of the record is proportional to the rotational speed. The faster the vinyl record turns, the wider the frequency of its response, but this A problem arises – the shortening of the recordable time. This is because in the early stage of the development of the record, the technology was not mature enough, and the record had to maintain a wide response frequency at a high speed and bring out a guaranteed sound quality, resulting in a shortage of recordable time. Since 1948, 33 1/3 rpm vinyl records have been released. After several years of rapid development, the single-sided recording time of the record has been increased to about 30 minutes, which is much longer than the previous recordable time. This is named Long Playing (the original vinyl record was called SP, Standard Playing). The new vinyl LP has gradually occupied almost all the market share because it is superior to the old SP in terms of technology and sound quality. Today, LP has completely become synonymous with vinyl records.
