MAGNETIC RECORDING HEAD HAVING PROTECTED READER SENSORS AND NEAR ZERO RECESSION WRITER POLES
First Claim
1. An apparatus, comprising:
- 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, wherein the first protection structure includes a recessed portion of the media facing side adjacent the first transducer; and
wherein the second transducer is protected by a second protection structure that is different than the first protection structure, wherein the second protection structure includes a recessed portion of the media facing side adjacent the second transducer,wherein an extent of recession of the recessed portion of the media facing side adjacent the second transducer is not as great as an extent of recession of the recessed portion of the media facing side adjacent the first transducer.

Abstract
An apparatus according to one embodiment includes a module having first and second transducers of different transducer types positioned towards a media facing side of the module. The apparatus also includes a first protection structure for protecting the first transducer. The first protection structure includes a recessed portion of the media facing side adjacent the first transducer. The second transducer is protected by a second protection structure that is different than the first protection structure. The second protection structure includes a recessed portion of the media facing side adjacent the second transducer. An extent of recession of the recessed portion of the media facing side adjacent the second transducer is not as great as an extent of recession of the recessed portion of the media facing side adjacent the first transducer.
