Abstract
A tape is associated with a semiconductor memory storing the end position of the last data of a data set recorded on the tape. The end location is stored in the memory before the last data are written to the tape. In a further operation mode, data identifying the location of one or plural successfully written data sets which have already been written to the tape are stored in the memory while user data are written to the tape.
