Compactified B Tapes

The DLT tapes written during the experiment are not filled up to the full capacity for a variety of reasons. It is therefore possible to produce `compactified' tapes, which contain all the runs on a much smaller number of volumes. Following an ALADiN tradition this second tape generation is called B Tapes, while the original tapes are called A Tapes.

In the production of the B Tapes we try to fill them to about 96-98%. Going beyond that can result in difficulties when 1-to-1 copies of those tapes are produced. Due to the varying data compression factor (it is high for pulser and test runs and lower for physics runs) one gets between 12.4 and 16.4 Gbyte data on a single DLT tape volume. Up to now, the following B Tapes have been produced:
