ABSTRACT:
The present invention provides a measurement apparatus for obtaining a suitable position on a suspension where a more miniature magnetic head slider is to be mounted to the suspension, the apparatus including a front camera having a photographing optical axis within a plane parallel to a plane of extension of a suspension and directed to the suspension, and a side camera having a photographing optical axis within the parallel plane and which is different from that of the front camera. Coordinates of a top portion of a convex surface of a dimple formed in the suspension are obtained with these cameras. The resultant coordinates and coordinates of the deepest portion of a recess surface of the dimple are correlated with each other, whereby in actual mounting of the magnetic head slider, the deepest portion of the recess surface of the dimple which is readily recognized is measured.
