ABSTRACT:
Systems and methods for managing operation of multiple tape drives in a way so that incoming data is spread or distributed across the multiple tape drives and which may be implemented in one example to continuously accept for recording without interruption from one or more data sources, for example, so that the date is distributed across the multiple tape drives in real time and without interruption as it becomes available from one or more given data sources. Two or more tape drives may be further be managed in a manner such that the multiple drives appear to be a single drive when writing data to, or reading data from, the multiple tape drives.
