[2] The agreement between Sony and Panasonic to jointly develop the next generation optical media standard was first announced on 29 July 2013.

[1][2][7][8] The Archival Disc standard jointly developed by Sony and Panasonic used signal processing technologies such as narrow track pitch crosstalk cancellation, high linear density inter-symbol interference cancellation and multi-level recording.

The track pitch is 0.225 μm, the data bit length is 79.5 nm, and the standard will utilise the method of Reed–Solomon Code error correction.

[9] In 2020, Sony began shipping their Gen3 PetaSite Optical Disc Archive, which could store up to 2.9 PB of data.

[1] The disc format was not intended as a consumer storage medium as of 2014, but rather for professional-level data archives.
