ABSTRACT:
One of the cartridge-type magnetic tapes set in a magazine is loaded into a magnetic tape unit, the magnetic tape thus loaded is data processed in the magnetic tape unit, and the data processed magnetic tape is then unloaded from the magnetic tape unit to be received into the magazine. This series of operations is sequentially repeated for all of the magnetic tapes set in the respective magazine steps. It is judged whether or not the data processed magnetic tapes set in the magazine have been replaced with fresh magnetic tapes yet to be data processed in the middle of the series of operations. If it is decided that the replacement of magnetic tapes has been done, the abovementioned series of operations, namely, the handling operations including the loading of a magnetic tape, data processing of the magnetic tape and receiving (unloading) of the magnetic tape, are continuously done for the magnetic tapes initially set in the magazine but yet to be data processed as well as the magnetic tapes replaced in the magazine and which are yet to be data processed.
