    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： There is disclosed a magnetic head device in which a head IC chip may be located relatively closer to a magnetic head and a thermal effect may be controlled to be within a range of acceptable degree. Said magnetic head device comprises a head slider having a magnetic head, a suspension member which is made of thin resilient material and supports the head slider at one end thereof, and a head IC chip, wherein the suspension member is attached to other member at the other end thereof. The IC chip is mounted on the suspension member. When the IC chip is selected to have appropriate disc side area and is mounted on the suspension member, the temperature of the IC chip itself may be maintained within a range of acceptable degree and that of the magnetic head may be also kept to be lower. When the electric power consumption of the IC chip is equal to or less than 410 mW, the disc side area thereof should be equal to or more than 1.1 mm2. The IC chip is mounted on a surface of the suspension member at a side facing to the disc at a position where a relative linear velocity equal to or more than 25 m/sec is generated with respect to said disc.

    摘要： A thin-film magnetic head that shows stable read and/or write performances, maintaining the reliability over time by suppressing the wear of the head sufficiently, is provided. The head comprises: a substrate having an element-formed surface and an opposed-to-medium surface; a magnetic head element; an overcoat layer formed on the element-formed surface so as to cover the magnetic head element; a closure provided on the overcoat layer, a surface of the closure being in contact with the upper surface of the overcoat layer; and an element contact pad formed in a sliding-side surface of the head and having a contact surface including a part of the opposed-to-medium surface, a part of an end surface of the overcoat layer and a part of an end surface of the closure, one end of the magnetic head element reaching the contact surface.
