FILLED-GAP MAGNETIC RECORDING HEAD AND METHOD OF MAKING
A magnetic head, according to one embodiment, includes a rowbar substrate having a tape support surface and a gap surface at a substrate edge. A closure is positioned opposite the gap surface of the rowbar substrate, the closure forming a portion of the tape support surface. A recessed gap region is interposed between the gap surface of the rowbar substrate and the closure, the recessed gap region having a recessed gap profile that extends between the gap surface of the rowbar substrate and the closure, the recessed gap region having a transducer row with at least one magnetic sensor on the gap surface of the rowbar substrate. An insulation layer is positioned over the recessed gap profile of the recessed gap region.
Method of forming magnetic recording head having protected reader sensors and near zero recession writer poles
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.
TAPE HEAD HAVING SUB-AMBIENT CHANNEL AND METHODS OF MANUFACTURE
An apparatus, according to one embodiment, includes a module having a tape bearing surface, an array of magnetic transducers, and a channel in the tape bearing surface. The channel has a longitudinal axis oriented about parallel to a longitudinal axis of the array of magnetic transducers for inducing tenting of a moving magnetic recording tape above the array of magnetic transducers. Moreover, the channel has a shape with a middle section of similar recession therealong between straight opposite ends.
Filled-gap magnetic recording head and method of making
A method of making a magnetic head, according to one embodiment, includes supplying a magnetic recording head having a gap disposed between a rowbar substrate and a closure, said rowbar substrate and closure having a tape support surface, recessing the gap below the level of the tape support surface, sputter cleaning the head, and depositing an insulation layer on the tape support surface and the recessed gap. In addition, about an entire upper surface of the insulation layer above the gap is recessed from the tape support surface.
