摘要：
A magnetic head according to one embodiment includes a module, the module having first and second transducers of different transducer types positioned towards a 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; 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.
