Abstract

Described is a method of supporting a multi-level naming structure where any given folder or subdirectory in a System/36 may contain data objects on multiple volumes while requiring at most one volume mount to find any specific data object. This addresses problems associated with searching through multiple optical volumes to locate an object leading to excessive overhead and time due to the movement of the media within a mass optical storage device (MOSD). In addition, limiting the number of volumes accessible through a single folder requires significantly more direct access storage device (DASD) overhead then a solution where multiple volumes are accessed through a single folder.
