Abstract
A method for managing data transfer from at least one input tape to an output tape begins by opening the output tape. For each input tape, the input tape is opened and directory information about the opened input tape is gathered. Data is read from the opened input tape, the data is encrypted, the encrypted data is written to the output tape, and the input tape is closed. The directory information for each input tape is written to a directory file on the output tape and the output tape is closed.
