The Australian Record Company (A. R. C.) was a Sydney based recording company that existed as an independent entity from September 1938 to 1960 (in October 1953, it was transformed from a privately held (proprietary) company (Pty. Ltd.) into a public one), then acquired by CBS, which, in turn, was acquired by Sony in 1991. The name Australian Record Company was in use until October 16, 1977.
The company had several own labels and also produced records for several small independent companies under their labels, such as, for example, Olympia / Cosmopolitan and Carinia (the initial releases with catalog numbers PM-101 ... PM-114; later the same records were pressed by EMI Australia). ARC-made masters were typically marked MX-nnnnn.
