摘要： Servo patterns and associated methods of fabricating servo patterns are described. For patterned storage media, data sectors and servo sectors may be patterned using self-assembly. In one embodiment, self-assembly is used to form a first array of islands and a second array of islands in servo sectors that are track-wise offset. A servo writing process is then performed to write a desired servo pattern in the arrays, such as for burst fields, synchronization fields, etc.

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.

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.

摘要： Methods of defining servo patterns and data patterns for forming patterned magnetic media are described. For one method, a lithographic process is performed to define a servo pattern in servo regions on a substrate. The lithographic process also defines a first data pattern in data regions of the substrate. The first data pattern is then transferred to (i.e., etched into) the data regions. Self-assembly structures are then formed on the data pattern in the data regions to define a second data pattern. The servo pattern is then transferred to the servo regions and the second data pattern is transferred to the data regions. Thus, the servo pattern is defined through lithographic processes while the data pattern is defined by a combination of lithographic processes and self-assembly.

摘要： A thin film, perpendicular write head for use with recording media with or without a soft under layer is disclosed. The present invention comprises an tapered auxiliary pole, situated below the main write pole and separated from the write pole by a lower non-magnetic gap. The auxiliary pole alleviates problems such as erasure after write, and cross track stray erasure fields, associated with operating conventionally designed perpendicular writes heads with media having no soft under layer.
