- Music producers
- Regulatory bodies
Why should you use BS EN 61909 - Audio recording minidisc system?
The premastered part of the disc contains a spiral shaped track, consisting of narrow shallow depressions, called pits, in a reflective or a magneto optic (MO) layer. The encoded audio or data information is stored in the length of these lengths and distances only take discrete values.
BS EN 61909 discusses disc specification, optical stylus, and cartridge, pregroove modulation, EFM modulation, ACIRA error correction system, sector data structure, and audio data. This will help you to understand the mechanical and electrical characteristics necessary to ensure interchangeability.
