This article relates to a method for providing uniform addressing of data stored on a range of secondary storage devices. The data is addressed in strings of blocks of a given length where the length may be different for each string of blocks. More particularly, the invention it describes a method for the device independent addressing of data stored on a plurality of serially reusable devices (direct-access storage devices) shared by many CPUs. The method utilizes several constructs for masking physical storage boundaries, thereby enhancing block storage management among device mixes. The constructs include a monotomically numbered space (DFE) corollated with discernible physical space, a zero remainder ratio (ARC) of n+DFE/block size, an index (DN) within DFE, a block count (ABC), an offset (RA) and a pointer (EL).
