In December 2021, ECMA-420 was published. The standard specifies device interface information and requirements for high-speed image retrieval and collation using holographic optical correlation based on shift-multiplex recording of coaxial holography.
In 2019, a 4th edition of ECMA-119 was published. The standard specifies the volume and file structure of compact read only optical disks (CD-ROM) for the interchange of information between users of information processing systems and the 4th edition incorporates, in Annex C, a description of the Joliet specification, which defines an extended volume space.
TC31 has several projects in development which include a standard on a quality discrimination method and operating method of storage systems for long-term data preservation. The standard will enable to build data storage systems using optical disks for storing and accumulating important digital information safely and on a permanent basis. TC31 also plans to develop a standard defining a holographic data storage system with a capacity of 1000 Gbytes per disk, which will enable building long-term data preservation storage systems with features such as high capacity, long-term reliability and lower operational costs.
