            Abstract : 
Demagnetizing effect on the recorded media in parametric reproduction process is described. The cause of the demagnetization is analyzed experimentally and a ditch-type head is proposed for the reduction of the demagnetization. The operation of the head is proved compared with that of a ring-type head
