A magnetic head and method for making same which can be used for formatting or writing servo tracks or data on a tape. In one example, the magnetic head may include a magnetic thin film layer; at least one gap defined in the magnetic thin film layer; and at least one secondary sub-gap structure within the magnetic thin film layer, the at least one gap positioned proximate the at least one secondary sub-gap structure. Through the use of the secondary sub-gap structure, the gap (i.e. a record gap or channel) can be made thinner than in conventional heads.
