Definition of Archival Disc
Archival Disc (AD) is the trademarked name of a discontinued optical disc storage medium designed by Sony and Panasonic for long-term digital storage. First announced on 10 March 2014 and introduced in the second quarter of 2015, the discs were intended to withstand changes in temperature and humidity, in addition to dust and water, ensuring that the disc would be readable for at least 50 years. The agreement between Sony and Panasonic to jointly develop the next generation optical media standard was first announced on 29 July 2013. The discs were mass-produced by Panasonic in 2016. The product was discontinued as of 2024. The two companies have since collaborated on the development of another format, Optical Disc Archive.
