Abstract:
A method according to one embodiment includes recessing a portion of a media facing side of a 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 one of the first transducers, wherein the recess forms 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.
