Abstract:
A magnetic head-positioning system to accurately test a magnetic disk and a magnetic head, comprises a plurality of hinges attached on an end portion of a linear driving element and disposed on both sides of a center line of the linear driving element, which is in parallel with an extension-shrinkage direction of the linear driving element, and an arm having a length longer than a distance between a plurality of hinge joint portions, the plurality of the hinge joint portions each of which join the hinge with a root portion of the arm and which are disposed on both sides of a center line of the arm which is in parallel with a longitudinal direction of the arm. The arm has an extremity portion on which a head gimbal assembly is detachably attached and this head gimbal assembly is positioned.
