摘要： A flexure 11 has a substrate 13 made of a thin conductive metal plate, a base insulating layer 31 made of flexible resin formed on the substrate, wiring patterns 15 formed on the base insulating layer and connected to a slider mount 17, and a cover insulating layer 33 formed over the wiring patterns. The flexure 11 is substantially coated with a conductive polymer layer 39 having a thickness in the range of 18 to 130 nm. The flexure 11 prevents electrostatic accumulation and ion migration that are trade-offs.

摘要： A method detects one or more cracks in a piezoelectric element interposed between a pair of electrodes and deforms according to a voltage applied thereto through the pair of electrodes. The method includes steps of applying a voltage at least at a resonance frequency of the piezoelectric element to the piezoelectric element through the pair of electrodes, measuring a dielectric tangent between the pair of electrodes under the applied voltage, and detecting if there are cracks in the piezoelectric element according to the measured dielectric tangent. The dielectric tangent of the piezoelectric element at the resonance frequency has a large peak or no peak depending on whether or not the piezoelectric element has cracks. Accordingly, the method easily and surely detects if the piezoelectric element has cracks according to the dielectric tangent of the piezoelectric element measured at the resonance frequency.

摘要： A leaf spring load measuring device of the present invention comprises a weighing mechanism, a measuring mechanism, a metering mechanism, and a control mechanism. The weighing mechanism applies a load heavier than a working load to a leaf spring, thereby bending the leaf spring in its thickness direction, and maintains the resulting state for a predetermined hold time. The measuring mechanism measures a load value of the leaf spring in a manner such that the spring is subjected to a load within a range of the working load. The metering mechanism meters a displacement of the spring when the load value is measured. The control mechanism controls the weighing mechanism, the metering mechanism, and the measuring mechanism, and has a timer function to meter the hold time.

摘要： A method corrects a head suspension by irradiating an objective part of the head suspension with a laser beam before or after mounting a read/write head on the head suspension. The method can precisely correct the head suspension even when correcting the head suspension a plurality of times. The method includes drawing, with the laser beam, a straight line of predetermined length on the objective part and repeating this process a plurality of times in such a way that the direction of a straight line drawn this time crosses the direction of a straight line drawn last time.

摘要： A method corrects a head suspension by irradiating an objective part of the head suspension with a laser beam. The method is capable of precisely correcting the head suspension even when correcting the head suspension a plurality of times. The method removes residual stress created by the preceding correction from the head suspension, and then, carries out the next correction. Accordingly, the method can precisely correct the objective part of the head suspension with a laser beam even if the objective part has once been irradiated with a laser beam in the preceding correction.
