Method and system for providing a magnetic recording transducer using a line hard mask
A method and system for fabricating a magnetic transducer is described. The transducer has a device region, a field region, and a magnetoresistive stack. The method and system include providing a hard mask on the magnetoresistive stack. The hard mask is inorganic and includes a sensor portion and a line frame. The sensor portion covers a first portion of the magnetoresistive stack corresponding to a magnetoresistive structure. The line frame covers a second portion of the magnetoresistive stack in the device region. The method and system include defining the magnetoresistive structure in a track width direction using the hard mask and providing at least one hard bias material after the magnetoresistive structure is defined. A first portion of the hard bias material(s) is substantially adjacent to the magnetoresistive structure in the track width direction. The method and system also include removing a second portion of the hard bias material(s).
