Archival Disc (AD) is the name of a discontinued trademark owned by Sony and Panasonic describing an optical disc storage medium designed for long-term digital storage. First announced on 10 March 2014 and introduced in the second quarter of 2015, the discs are intended to be able to withstand changes in temperature and humidity, in addition to dust and water, ensuring that the disc is readable for at least 50 years.[2] The agreement between Sony and Panasonic to jointly develop the next generation optical media standard was first announced on 29 July 2013.[3]
The discs were mass produced by Panasonic in 2016.[4]
