20120057446 | SUB-OPTICAL-RESOLUTION KERR SIGNAL DETECTION FOR PERPENDICULAR WRITE-HEAD CHARACTERIZATION - A property, such as a quality parameter, of a write pole in a write head is determined using an optical metrology device, where the write pole is smaller than the optical resolution limit of the metrology device. The metrology device produces polarized light that is reflected off the write pole while the write pole is magnetized either during or after excitation with a write current. The magnetization alters the polarization state of the light, which can be analyzed to transform the altered polarization state into intensity. The intensity of the light is detected over the point spread function of the optics in the metrology device and an intensity value is generated. The intensity value is used to determine the quality parameter of the write pole, e.g., by comparison to a threshold or reference intensity value, which may be generated empirically or theoretically. | 03-08-2012 |

Magnetization in the write head produces a magnetization in the magnetic layer, which alters the polarization state in reflected light. The reflected light is analyzed and the intensity detected using an optical detector, such as one or more photo-detectors or a camera. The performance of the write head can then be characterized using the detected intensity. | 04-19-2012 |
20130257461 | METROLOGY FOR CONTACTLESS MEASUREMENT OF ELECTRICAL RESISTANCE CHANGE IN MAGNETORESISTIVE SAMPLES - A metrology device optically measures the electrical conductivity of a magnetic sample, such as a Tunneling Magnetoresistance (TMR) or Giant-Magneto Resistance (GMR) device, using Time Domain Thermo Reflectance (TDTR) to measure a cooling curve for the sample while a magnetic field is applied to the sample. The thermal conductivity of the sample may be determined using the cooling curve and the variation of the cooling curve with varying applied magnetic fields is measured. The electrical conductivity is determined for the sample in the magnetic field based on the thermal conductivity. If desired, single reflectance changes may be measured at a particular delay after heating, and the reflectance change at this delay may be used to determine the electrical conductivity. Of particular interest is the amount of change in electric conductivity for a given applied magnetic field because this yields a measure of the sensitivity of the sensor. | 10-03-2013 |
