ABSTRACT:
This method provides new data storage capabilities that are implemented within the industry standard formats of mountable media data recording devices. The new data storage structures are written into regions presently marked on the mountable media as "contents of this region are not of interest" or marked as "no data was recorded within this region". These data storage structures are transparent to present data recording devices and do not disrupt their data processing functions. However, the data storage structures are available to new data recording devices so that new data embedded therein is used to enhance the functionality of the system which utilizes these data storage structures. The types of embedded data may include ECC (error correction codes), tape position information, audit information, security information, mount history, media defect history, authentication notation, generation-identification notation, etc.
