Businesses in the reproduction of recorded media make copies of audio, video and data recordings on physical formats. Depending on their equipment and specialism, they may duplicate CDs, DVDs, Blu-ray discs, vinyl records, cassette tapes or other media, producing small or large batches. Customers can supply finished recordings, or use related services such as audio or video mastering, format conversion and preparation of files for manufacture. Typical work includes checking source material, transferring recordings to a suitable format, producing discs or other media, and applying printed labels or artwork. Packaging options may include sleeves, cases, inserts and boxed sets. Some providers also digitise recordings held on older or less accessible formats, or create copies for archiving and distribution. Reproduction is generally carried out from material supplied by the customer; customers are responsible for ensuring they have the necessary rights to copy and distribute it.
