ABSTRACT:
A new digital data storage system comprises at least one storage device, a memory and a control device. The storage device retrievably stores a series of records. The memory stores at least one descriptor for describing at least one selected format attribute of the records stored by the storage device, the selected format attribute having a plurality of formatting characteristics. The descriptor includes a series of record format flags, each of which is associated one of the series of records in the storage device. Each record format flag has a first condition indicating that the selected format attribute of the associated record has a predetermined format characteristic, and a second condition indicating that the selected format attribute of the associated record has a format characteristic which is identified elsewhere in the descriptor. The control device uses the record format flags of the descriptor in connection with retrievals of ones of the records from the storage device.
