We describe the organization of a general purpose data archival system for Write‐Once, Read‐Many (WORM) optical disks. The system has been designed for large‐scale and long‐term data storage and retrieval. The archival system is independent of the operating system, flat, self‐consistent, does not use any write cache on magnetic disk, and allows the exploitation of auxiliary information on magnetic disk, which can be rebuilt immediately in case of a crash, to speed up file retrieval. A library in C language, called pODLIB, has been implemented as a portable interface to the archival system.
