    摘要: Disclosed is a glide head for a magnetic disk that has a high sensitivity for efficiently transmitting a vibration due to a defect of a magnetic disk to piezoelectric element and the like and has high abrasion resistance and a long service life. The glide head is resiliently held at an end of a suspension arm through a flexure and has a slider, a load point of which a pressing force from the suspension arm is applied to through a pivot disposed on the flexure. The slider comprises two sliding rails that protrude from a bottom surface of the slider, extend from a leading end of the slider to a trailing end of the slider, parallel to and at a distance from each other, and have near the trailing end of the slider a rear edge that works as a sensor for detecting the defect of the magnetic disk. Each sliding rail has an upstream floating surface positioned within a region from the slider leading end to the load point and a downstream floating surface within a region from the load point to the slider trailing end so that the slider has a floating pitch angle from 140 to 380 μrad. A length of the upstream floating surface is preferably from 0.67 to 0.91 as expressed by a ratio to the total floating surface length.

    摘要: An optical power monitor comprising a pig-tail fiber and a GRIN lens opposed to each other with a spacing and each having an end face (angled face) angled with respect to the axis, being low on reflection loss and able to be easily assembled. The pig-tail fiber and the GRIN lens are fixed in respective sleeves having axial end faces adhered to each other. At least one of the pig-tail fiber and the GRIN lens has an arc-segmental end face directed in its axial direction at the tip of its angled face. The arc-segmental end face is positioned in the same plane as the axial end face of the sleeve of the one. The axis of the sleeve of the one is kept vertical to the axial end face of the sleeve of the one. It can be prevented that the axial tip of the other enters the sleeve of the one and comes into contact with an inner wall of the sleeve of the one. Therefore, the assembling man-hours needed to adjust their relative positions can be reduced, and the assembling yield can be improved.

The average crystal grain size of the thin film copper coil is made to be not more than 0.5 &mgr;m. More preferably, the average crystal grain size should be not more than 0.2 &mgr;m. In the thin film magnetic head, the surface roughness of the thin film copper coil can be reduced to not more than 15 nm.

    摘要: A manufacturing method that can manufacture small thin film magnetic head sliders with high dimensional accuracy and high manufacturing yield is disclosed. This manufacturing method uses 5 inch- or 6 inch-dia. substrate wafers having a thickness sufficient to keep wafer bending to a minimum level even after thin film magnetic head elements have been formed on it. On the front side surface of the substrate wafer formed are thin film magnetic elements. After a protective layer covered on the surface of the thin film magnetic head elements has been ground and/or lapped, the back side surface of the substrate wafer is ground and/or lapped to a thickness equal to a desired slider length.
