    Optical Storage Technology Association (OSTA)

    The Optical Storage Technology Association was an international trade association formed to promote the use of recordable optical data storage technologies and products. It was responsible for the creation and maintenance of the Universal Disk Format file system specification, which was notably adopted for DVD-Video. It was incorporated in California in 1992 and dissolved in 2018.
