Apparatus, for duplicating magnetically recorded information by contact transfer from a master medium in the form of a magnetic rotatable drum to a slave medium in the form of a magnetic tape, includes a magnetic head, for initially recording the information to be duplicated on the magnetic drum, having a media-contact surface the curvature of which conforms to the curvature of the drum. The magnetic head is mounted with its media-contact surface essentially parallel with the surface of revolution of the drum, thereby enhancing signal-to-noise performance by suppressing spacing losses.
