Hey Kevin, According to IASA Cataloging Rules, you would use the quantity and specific material designation "sound disc" followed by the specific format term in parentheses. Two examples from IASA: 1 sound disc (metal mother) 1 sound disc (lacquer) IASA's cataloging rules for physical description are here: http://www.iasa-web.org/special_publications/cataloguing_rules/05_B.htm Beyond the limited format list there (Section 5.B.2.), IASA suggests additional format terms may be applied as appropriate.
