1. A method, comprising:

  • recessing a portion of a media facing side of a tape head module, the module having first and second transducers of different magnetic transducer types positioned towards the media facing side of the module, wherein the different transducer types are selected from a group consisting of data reader transducers, servo reader transducers, write transducers, piggyback read-write transducers and merged read-write transducers;

    wherein the recess is positioned towards the first transducer,wherein the recess is filled with a layer, thereby forming a first protection structure for protecting the first transducer; and

    wherein the second transducer has either no protection or is protected by a second protection structure that is different than the first protection structure.
