    Abstract: A device for compensating for an inequality between the d.c. magnetic fields set up by the two oppositely acting windings, respectively, of the magnetic heads of a data storage device, particularly a disc memory, and a data storage apparatus including such a device, the device comprising means for generating a compensating direct current and feeding this current at the appropriate time to a predetermined one of the two windings of the magnetic heads. The magnitude of the compensating direct current is advantageously adjusted in dependence on the instantaneous magnitude of the write current.
