    摘要： The object of the present invention is to provide a write/read head supporting mechanism for a magnetic or optical disk system having a micro-displacement actuator, by which any impediment to the displacement capability of the actuator is eliminated. A write/read head supporting mechanism comprises a slider provided with an electromagnetic transducer element or an optical module, and a suspension. The slider is supported on suspension by way of an actuator for displacing slider. An electrical connection to the electromagnetic transducer element or said optical module is made by a first interconnecting arrangement movable and/or deformable in the displacement direction of slider by actuator, and an electrical connection to actuator is made by a second interconnecting arrangement.

    摘要： The object of the invention is to provide a write/read head supporting mechanism for a magnetic or optical disk system having a micro-displacement actuator, by which any impediment to the displacement capability of the actuator is eliminated to achieve reliability improvements. The write/read head supporting mechanism comprises a slider, a suspension and an actuator as at least head constituents. The slider is provided with an electromagnetic transducer element or an optical module. The slider supported on the suspension by way of the actuator is displaceable relatively with respect to the suspension by the actuator. Between relatively displacing head constituents there is a space. Preferably, friction-reducing means should be provided in the space.

    摘要： A method of testing a performance of the HGA has a step of writing information from the at least one thin-film magnetic head element onto a magnetic disk with driving the actuator for displacement by applying an alternating drive signal to the actuator, a step of reading out the information of at least one rotation of the magnetic disk by the at least one thin-film magnetic head element without driving the actuator for displacement, a step of storing the information read-out from the magnetic disk as a read-out information along a disk-rotating direction, a step of moving the HGA toward an off-track direction by a predetermined distance, a step of repeatedly executing the reading, storing and moving steps to obtain two-dimensional read-out information along the disk-rotating direction and the off-track direction, and a step of determining, from the two-dimensional read-out information, an off-track position where the read-out information becomes maximum at each position along the disk-rotating direction, the determined off-track positions being recognized as displaced positions of the actuator in response to the applied alternating drive signal.
