摘要： In the formation of an AlN film as a gap layer of a thin film magnetic head, the mean crystal grain size of the AlN film can be regulated in the range from 85 angstroms to 130 angstroms to improve the denseness of the film, by connecting a radio frequency power source also to a substrate-supporting unit and supplying bias power of 17 W to 40 W to the substrate-supporting unit. The AlN film can have, therefore, improved head dissipation, corrosion resistance against an alkali solution, higher hardness, higher surface resistance and lower surface roughness. There is also disclosed a thin film magnetic head comprising at least a magnetoresistive element layer formed on a lower shield layer with the interposition of a lower gap layer, a lead layer for imparting a sensing current to the magnetoresistive element layer, and an upper shield layer formed on the lead layer with the interposition of an upper gap layer, in which at least either of the lower and upper gap layers has an Al—N—X system insulating layer, the element X being at least one element selected from Si, B, Cr, Ti, Ta and Nb.

摘要： A supersonic flaw detecting system has a probe adapted to emit a supersonic wave towards an object to be inspected, a scanning device for causing a relative movement between the probe and the object in two orthogonal directions, a pulser-receiver adapted to supply pulses to the probe and receive the supersonic wave from the object and produce an electric signal indicative thereof, a signal processing device for converting the electric signal from the pulser-receiver into an image data signal for a C-scope display, an oscilloscope for conducting an A-scope display of the electric signal from the pulser-receiver, and a monitor T.V. having a screen for conducting the C-scope display of the image data signal from the signal processing device. A control unit when the probe and object are relatively moved by the scanning device, the image data carried by the image data signal from the signal processing device at a corresponding address in the image memory at each pitch which has been determined such that the number of data pickups during the relative movement between the probe and the object coincides with the number of the corresponding addresses in the image memory to thereby cause C-scope display of the image data to be effected on the screen. The is operative to compute, when the cursor is displayed on the screen by the operation device, the amount of operation of the scanning device necessary for locating the probe relative to the object at a position corresponding to the cursor on the screen and operate the scanning device by the thus computed amount to locate the probe at the corresponding position, thereby permitting A-scope display to be effected at such a position on the oscilloscope.

摘要： A lower shield layer has a substantially flat shape, and an upper shield layer has a front portion and a rear portion, where the front portion is disposed closer to the lower shield layer than the rear portion. A lower conductive electrode and an upper conductive electrode are disposed between the lower shield layer and the upper shield layer. The lower conductive electrode is electrically connected to the lower shield layer, and the upper conductive electrode is electrically connected to the upper shield layer. Since the lower and upper conductive electrodes are disposed between the upper and lower shield layers, each of the lower shield layer and the upper shield layer may be formed to have a small area and a simple shape.

摘要： A CPP giant magnetoresistive head includes a lower shield layer; an upper shield layer; and a giant magnetoresistive element (GMR) between the lower shield layer and the upper shield layer. The GMR includes a nonmagnetic material layer; a pinned magnetic layer; and a free magnetic layer. The pinned layer and the free layer are laminated with the nonmagnetic layer provided therebetween. A current flows perpendicularly to a film plane of the GMR, the pinned magnetic layer extends in the height direction longer than in a track-width direction and includes a first portion in the GMR. The first portion is disposed above or below the nonmagnetic layer and the free layer. A second portion is behind the nonmagnetic layer and the free layer in the height direction. The first and second portions are in the same plane. The width of the pinned layer in the track-width direction in the first portion is greater than that in the second portion.
