Abstract
In a magnetic storage system including a data conversion unit for performing reading or writing of data from or to a magnetic tape medium, and a system control unit, the data conversion unit has a plurality of electromagnetic transducers which are arranged so as not to overlap with one another in a travel direction of each of a plurality of recording tracks provided on the magnetic tape medium, and performs the reproduction of the data from each reproducing track using one of the electromagnetic transducers a plurality of which are assigned every recording track. In the system control unit, an error included in the regenerative data is detected. When an error is detected, the one electromagnetic transducer which performed the reproduction when detecting an error of the data is switched to another electromagnetic transducer assigned every recording track, thereby to perform the reproduction properly.
