For facilitating nondelete recordings, such as in magnetic recording or write-once optical media, directories are built contemporaneously with the storage of data. Various directories are distributed with the data for facilitating indexed accessing. An address space is divided into a predetermined number of divisions. One of the divisions is restricted to containing a first level directory. The remaining divisions are data storage areas each with an optional set of concatenated directories, which are referred to by the first level directories. An address space is shown as being divided into a plurality of divisions. The upper-mode division stores the first level directory. This division is divided into a number of areas corresponding to the number of data storing divisions.
