Abstract—Conditions have been considered concerning changes in the parameters of a sawtooth magnetiza- tion transition with allowance for the coercive force of the magnetic carrier during the action of an external mag- netic field (process of recording) and in the absence of an external field (process of demagnetizing). Expressions have been obtained for the calculation of parameters of the sawtooth transition in an external field and of the magnetostatic energy of the transition. Examples of the calculation of the sawtooth transition are given for var- ious values of the coercive force of the magnetic carrier.
