Optical Storage Technology Association

The Optical Storage Technology Association (OSTA) 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 (UDF) file system specification (derived from ISO/IEC 13346 and ECMA-167), which was notably adopted for DVD-Video.

The web site of the association provides the full digital specification books of each revision of the Universal Disc Format (UDF) starting at 1.02, as well as other whitepapers and information pages related to optical data storage.

[4] In 2003, the MythBusters visited David Bunzel at the OSTA for an experiment, in which the speed at which discs can be spun before shattering was tested.

The error stems from assuming a linear velocity of 52× at the inner edge of the data area of the disc (see CD-ROM § speed table).
