A method for the simultaneous recording of magnetic resonance data relating to an examination subject from at least two different slices by a magnetic resonance sequence, wherein an excitation period of the magnetic resonance sequence that includes at least one sub-section that acts on only one of the slices, and that contains at least one high frequency pulse is used, wherein, to correct the main magnetic field inhomogeneities of the first order, for each slice affected by a sub-section, a correction parameter that modifies the gradient pulses that are to be emitted is determined, taking into account at least one main magnetic field map that describes the spatial distribution of the main magnetic field and a slice position of the affected slice and is applied in the emission of gradient pulses for the respective slice in the sub-section.
