Abstract: Embodiments described herein generally relate to connecting electronic lapping guides (ELGs) to a lapping controller to prevent the effects of current crowding while reducing connections to the ELGs in single pad lapping. Devices and systems can include a row of sliders including a magnetoresistive (MR) element, a plurality of high resistance ELGs connected to both the wafer and to at least one bonding pad and at least two peripheral grounding vias connected to the wafer. Methods and systems include a wafer comprising a plurality of sliders wherein each slider is connected to a lapping controller and the delivery of current to the ELGs is sequential to groups of sliders such that only one group of ELGs is being measured at any time.

Abstract: Embodiments described herein generally relate to connecting Electronic Lapping Guides (ELG) to a lapping controller to reduce resistance from current crowding while reducing connections to the ELG. A device and a system can include a wafer with peripheral grounding vias having a radius of at least 10 ?m, a plurality of sliders with a magnetoresistive (MR) elements; a plurality of ELG electrically coupled to the lapping controller through a combination of the wafer and grounding pads and a bonding pad electrically coupled to the ELG. The ELG or the bonding pad can be positioned in the kerf or the device region of a row. If the ELG and the bonding pad are positioned in separate regions, a noble metal should be used to connect. Further, the number of grounding pads can be reduced by using grounding vias at specific intervals and specific sizes.

Abstract: A magnetic head having non-GMR shunt for perpendicular recording and method for making magnetic head having non-GMR shunt for perpendicular recording is disclosed. A shunt is provided for shunting charge from a read sensor. The shunt is formed co-planar with the read sensor and is fabricated using non-GMR materials.
