Information technology; data interchange on read-only 120 mm optical data disks (CD-ROM)

This document establishes technical specifications for the organization of data on 120mm optical read-only media, commonly referred to as CD-ROMs. It defines the fundamental structure required to ensure interchangeability between different systems and devices. The scope covers the layout of the disc, including the lead-in, lead-out, and program areas, as well as the specific file system and directory structures necessary for consistent data retrieval. By standardizing physical and logical parameters, this work facilitates seamless communication across diverse platforms without requiring proprietary adaptations. It addresses critical aspects such as sector size, error correction methods, and the formatting of volume descriptors. The guidelines provided enable manufacturers to produce compatible products and allow software developers to create applications that function reliably on various hardware implementations. Adherence to these technical guidelines supports the broader ecosystem of digital information exchange by reducing compatibility issues and promoting uniform data storage practices globally.
