Abstract: The magnetic head tester of the present invention drives a medium for rotation to float a slider from the medium so as to test a magnetic head for its characteristics, and the tester includes a holder removably holding the slider opposed to the surface of the medium, and suspension means provided in the holder which has the same function as a suspension supporting the slider in a real apparatus. With this tester, tests can be executed by exchanging the slider alone, and it is unnecessary to discard the suspension even when the magnetic head is judged to be defective, thus the loss of production costs for the suspension and processing costs for assembling the slider in the suspension can be avoided.

Abstract: The slider tester is capable of solely testing a slider and securely selecting good sliders so as to reduce wasteful costs. The slider tester, which tests reading and writing functions of a slider for reading data from and writing data on a recording medium, includes a testing device for testing the functions of the slider, and a setting plate holding the slider and electrically connecting the slider to the testing device. The setting plate separates the slider a prescribed distance from the recording medium during the test so as to read data from and write data on the recording medium, wherein the slider can be independently attached to and detached from the setting plate.

Abstract: The magnetic head tester of the present invention drives a medium (40) for rotation to float a slider (10) from the medium (40) so as to test a magnetic head for its characteristics, and the tester comprises a holder (20) removably holding the slider (10) opposed to the surface of the medium (40), and suspension means (24) provided in the holder (20) which has the same function as a suspension supporting the slider (10) in a real apparatus. With this tester, tests can be executed by exchanging the slider (10) alone, and it is unnecessary to discard the suspension even when the magnetic head is judged to be out or order, thus loss of production cost for the suspension and processing cost for assembling the slider in the suspension can be avoided.

Abstract: The small and light piezoelectric actuator of the present invention is capable of highly precisely positioning a magnetic head assemblies, etc. The piezoelectric actuator comprises: a movable member to which a head suspension is fixed; a fixed member fixed to a carriage arm; piezoelectric elements provided between the movable member and the fixed member and capable of adjusting a position of the head suspension by their deformation; and an electrode member electrically connected to one of electrodes of each of the piezoelectric elements. The movable member is adhered on the piezoelectric elements and electrically insulated from the other electrodes of the piezoelectric elements. The electric conductive layer of the electrode member and the other electrode of each of the piezoelectric elements are electrically connected to cables, which are provided to the head suspension so as to actuate the piezoelectric elements.

Abstract: An object of the present invention is to provide a head suspension, which can be assembled without damaging the head element. In the head suspension, a rigid section holds a head slider which writes data on and reads data from a disk. The rigid section is capable of bearing an external force whose direction is perpendicular to a recording face of the disk. A spring section has elasticity in the direction perpendicular to the recording face of the disk. An anti-vibration member is provided in the spring section, the anti-vibration member partially has a vacant space. With this structure, change of elastic pressure of the head suspension can be maintained within a proper range, transmitting the vibration to the head slider can be restricted, and the head slider can be floated stably.

Abstract: A head assembly including a suspension, a head slider mounted on a front end portion of the suspension and having a magnetoresistive element, and a pair of lead lines formed on the suspension and having first ends connected to the magnetoresistive element. The head assembly further includes a metal ball connected by bonding to the pair of lead lines. In handling the head assembly as a separate member, a current caused by static electricity flows through the metal ball short-circuiting the pair of lead lines, thereby preventing burning of the magnetoresistive element due to the current. After mounting the head assembly to an actuator arm, the metal ball is removed to electrically open the pair of lead lines.
