摘要： A slider is described with a resistive electro-lapping guide (ELG), which is aligned with a structure in the write head such as the throat height or trailing shield thickness and extends from the lapping region through the ABS and is connected to pads on the surface of the slider. In a second embodiment the ELG is disposed entirely in the section of the slider which will be removed by lapping. Another embodiment of the invention is a system for single slider lapping which simultaneously monitors the resistance of the read sensor or a read head ELG and at least one ELG that is aligned with a structure in the write head. A controller uses the resistance information to implement an algorithm which decides when lapping should be terminated.

摘要： Patterned media and associated methods of fabrication are provided in which vertical magnetic grains are grown on a patterned seed layer. The patterned seed layer includes a matrix of islands of a first seed material. Each island of first seed material is separated from other islands by a region of second seed material. The first seed material is selected to initiate growth of magnetic material, and the second seed material is selected to initiate growth of non-magnetic material. Subsequently, magnetic material is grown on the first seed material and non-magnetic material is grown on the second seed material. Deposition may be simultaneously. The magnetic and non-magnetic materials form well-defined vertical columns over the first and second seed materials respectively. Thus, each island behaves as an isolated magnetic unit, which switches independently from its neighbor units, which are magnetically separated by the non-magnetic material.

摘要： A structure for preventing Electrostatic Discharge (ESD) damage to a magnetoresistive sensor during manufacture. The structure includes a switching element that can be switched off during testing of the sensor and then switched back on to provide ESD shunting to the sensor. The switch can be a thermally activated mechanical relay built onto the slider. The switch could also be a programmable resistor that includes a solid electrolyte sandwiched between first and second electrodes. One of the electrodes functions as an anode. When voltage is applied in a first direction an ion bridge forms across through the electrolyte across electrodes making the resistor conductive. When a voltage is applied in a second direction, the ion bridge recedes and the programmable resistor becomes essentially non-conductive. Another possible programmable resistor uses a phase change material that can change between an amorphous high resistance state and a crystalline low resistance state upon the application of a certain heat treatments.

摘要： An improved method for the manufacture of magnetoresistive multilayer sensors is disclosed. The method is particularly advantageous for the production of magnetic tunnel junction (MTJ) sensors, which can be damaged at the air bearing surface by conventional lapping and ion milling. The disclosed process protects the ABS of the magnetoresistive sensor by depositing a diamond like carbon layer which remains in place through ion milling. The DLC layer is removed by oxidation subsequent to the formation of the ABS.
