摘要： In a manufacturing process of a head slider, a plurality of head elements are formed on a wafer, each head element comprising: a return pole, a coil, and a main pole. The wafer is cut into respective head elements so that individual head sliders are formed. A ratio of an amplitude of an electrical signal applied to the coil of the write head on the head slider to an amplitude of output from an independent magnetic field sensor not embedded in the head slider is calculated, where the independent magnetic field sensor is disposed near the main pole so as to be opposed to the main pole across the air bearing surface, and where the ratio is calculated while a displacement between the main pole and the magnetic field sensor is swept. A flare point height of the main pole is determined from the calculated amplitude ratio.

摘要： To enable measurement over a wide dynamic range from weak light quantity to strong light quantity in a light quantity detection device for detecting the light quantity, a detection signal from a photon counting light detector is A/D converted. When the A/D converted detection signal has a preset threshold value or more, the detection signal is transmitted as it is to a number-of-photons calculation circuit in a subsequent stage, and when the detection signal has the threshold value or less, threshold value processing for transmitting a preset reference value to the subsequent stage is performed. In the number-of-photons calculation circuit, the number of photons or the light quantity incident on the photon counting light detector is acquired from the dimension of an acquired detection signal waveform until the light quantity measurement ends.

摘要： In a signal transmission system, performing signal transmission via signal interconnections 4-1 to 4-3 between a memory 1 and a memory controller 2 mounted on a printed circuit board 3, noise or jitter may tend to be increased in the memory 1 and in the memory controller 2 at a specified data rate due to interconnection length resonance. Registers 6-1 and 6-2 are provided to hold information on the data rate. These registers 6-1 and 6-2 are provided in the signal transmission system along with a control system that modifies the relationship between clock frequency and interconnection length. The data rate or the propagation delay time is controlled to allow for avoiding the resonance.

摘要： Head elements are formed on a wafer to suppress deterioration in pinning strength of a pinned layer, which is caused by ESD generated during air bearing surface polishing of a thin film magnetic head. The wafer is cut into rovers in each of which are connected head elements. Rover air bearing surfaces are polished until an MR elements attain a predetermined height. A final polishing step finishes air bearing surfaces by applying an electroconductive polishing liquid to achieve a predetermined shape and surface roughness with high accuracy. A pinning defect occurrence rate is reduced by suppressing deterioration in pinning strength of a pinned layer of a read element. To achieve this, a specific resistance of the electroconductive polishing liquid is controlled to 5 GΩ·cm or less. A shallow rail and a deep rail are formed on the air bearing surfaces, and the rover is cut into thin film magnetic heads.

摘要： Head elements are formed on a wafer in order to suppress deterioration in pinning strength of a pinned layer, which is caused by ESD generated during a thin film magnetic head production process, particularly in an air bearing surface polishing step. The wafer is cut line by line into rovers in each of which the head elements are connected; surfaces to be used as air bearing surfaces of the rover are polished until an MR element height reaches to a predetermined value. After this air bearing surface polishing, an electroconductive polishing liquid is used in a final bearing surface polishing step of finishing the air bearing surfaces to achieve a predetermined shape with high accuracy and a predetermined value of a surface roughness. In order to suppress a pinning defect occurrence rate by suppressing deterioration in pinning strength of a pinned layer of a read element, a specific resistance of the electroconductive polishing liquid is controlled to GΩ·cm or less, preferably 1 GΩ·cm or less. After that, a shallow rail and a deep rail are formed on the air bearing surfaces, and the rover is cut to accomplish thin film magnetic heads.
