Sony will be using Archival Disc in the Optical Disc Archive professional archival product range. Both companies will market the optical format under their respective brands. In order to reach a larger capacity whilst ensuring higher playback signal quality, the standard will employ crosstalk cancellation and partial-response maximum-likelihood (PRML) signal processing. The disc format is not intended as a consumer storage medium as of 2014, but is intended by the two companies as a solution for professional-level data archival. Sony expects the new standard to see usage in the film industry (such as storage of 4K resolution audiovisual data ), archival services, and cloud data centres handling big data. Release timescales of the larger discs are currently unknown. In the summer of 2015, Sony was scheduled to release a roadmap plan to increase Archival Disc capacity from 300GB to 1TB per disc.

In 2019, Sony, co-developed with Panasonic, released it third generation Optical Disc Archival.

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. The disc structure will feature dual sides, with three layers on each side, and a land and groove format. The Archival Disc standard jointly developed by Sony and Panasonic will utilise signal processing technologies such as narrow track pitch crosstalk cancellation, high linear density inter-symbol interference cancellation and multi-level recording. The discs are designed to hold 300 gigabytes of data in their first release, then a second version of the discs will hold up to 500 gigabytes, and eventually a third version of the discs will be able to store up to one terabyte of data, based on the roadmap plans of both companies.
