3CD
3CD is a designation used in various domains, without a single universally accepted definition. In music and media industries, 3CD most often denotes a triple-CD release: a collection or box set consisting of three compact discs. Such releases may correspond to expanded editions, retrospectives, or soundtracks, and are frequently listed in catalogs and online stores with the "3CD" label. The format indicates that the product contains three separate discs rather than a single CD or DVD.
In consumer electronics and hardware contexts, 3CD can appear as a model number or specification shorthand
Beyond these uses, 3CD may appear as an acronym or code within specific organizations, standards, or cataloging
