ABSTRACT:
By recording an alternating signal in an ancillary recording medium having high coercivity, such medium will exhibit an external field of a given strength. The ancillary medium is placed in proximation to the record zone of a signal-carrying magnetic head cooperative with a primary magnetic recording medium of lesser coercivity, the fields of the head and ancillary medium algebraically adding to effect signal recording in the primary medium. When the field of the ancillary medium has a strength approximating the coercivity of the primary medium, the signal current applied to the magnetic head may be quite small.
