摘要： An improved magnetic head support mechanism intended for causing a magnetic head to float over a magnetic recording medium, comprises a spring member for retaining the magnetic head and a loading beam member provided with flanged portions along both longitudinal sides thereof and connected to the spring member at one end thereof and coupled to a shifting mechanism at the other end thereof and capable of giving the magnetic head an urging force to act on the magnetic recording medium. The loading beam member is penetratingly formed with at least one passing hole which permits the passing therethrough of an air stream generated by the rotational movements of the magnetic recording medium when the magnetic head is floating, so that it is possible to reduce the exciting force acting on the loading beam member and to thereby obtain the stabilized floating of the magnetic head.

摘要： A slider equipped with a magnetic head is pressed on a magnetic disk surface under a constant pressure by a pressing member. The slider is loaded and unloaded by a loading/unloading mechanism. A driving unit of the loading/unloading mechanism has a shape memory alloy member which offers a shape memory effect based on the thermoelastic martensitic transformation, and a resilient member having a resilient force against the driving force of the shape memory alloy member. Moreover, the loading/unloading mechanism is arranged such that when the slide is loaded, the driving force of the loading/unloading mechanism is not applied to the pressing member supporting the slider.

摘要： A magnetic head includes a gimbal with a head slider attached thereon, a load beam retained on the gimbal, and a mount attached on an end portion of the load beam on a side opposite to a side where the head slider is attached. A fulcrum portion as a center of load of the head slider is set on the gimbal to be shifted from a center of the head slider along its longitudinal direction to a proximal end side of the load beam, namely, toward an air upstream side. To compensate for the imbalance of the floating force due to the shift of the fulcrum portion, there is generated a moment about the fulcrum portion. The moment is provided by assigning an inclination angle to a slider attaching surface of the gimbal. The inclination angle can be adjusted by the height of the projection formed as the fulcrum portion. Moreover, the moment is generated by disposing rails on the head slider such that the width on the air upstream side of each rail is wider than the width on the air downstream side of the rail. This compensates for the variation in the load of the head slider and hence minimizes the change in the quantity of floating distance.
摘要翻译：一个磁头包括一个万向架，其上安装有头部滑块，一个保持在万向节上的负载梁，以及一个安装在负载梁端部上的安装头部滑块附近一侧的安装座。作为头滑块的负载中心的支点部分设置在万向节上，以从头滑块的中心沿着其长度方向移动到负载梁的近端侧，即朝向空气上游侧。为了补偿由于支点部分的偏移引起的浮力的不平衡，产生绕支点部分的力矩。通过向万向节的滑块附接表面分配倾斜角来提供该时刻。可以通过形成为支点部的突起的高度来调整倾斜角度。此外，通过在磁头滑块上设置轨道使得每个导轨的空气上游侧的宽度比轨道的空气下游侧的宽度宽。这补偿了磁头滑块的负载的变化，从而最小化了浮动距离的变化。

摘要： A core burying channel is formed on the outer side surface of an air bearing rail of a floating magnetic head floating on a magnetic disk by an air-flow in a direction perpendicular to a magnetic recording medium travelling direction, and a magnetic core is buried in this core burying channel. This magnetic head can be produced easily by a production method which forms a core burying channel in a non-magnetic block, then deposits a magnetic material to the core burying channel and removes unnecessary portions of the magnetic material.
