摘要： A pair of slits are defined in a slider body of a head slider so as to extend from a trailing end surface to the leading end on the slider body. A movable block is established in the slider body between the slits. The slits ensure the extent of movement for the movable block. Elongated plates enable a relative displacement between the movable block and a stationary block. A head element is mounted on a trailing end surface of the movable block. The thickness of a non-magnetic layer corresponds to the gap length of the head element. The gap length of the head element can easily be controlled based on deposition of the non-magnetic layer. The thickness of the non-magnetic layer can be reduced in a relatively facilitated manner, so that the gap length of the head element can easily be minimized.
摘要翻译：一个狭缝被限定在头部滑动件的滑块体中，以便从滑动件主体的后端表面延伸到前端。在滑块体之间在狭缝之间建立可动块。狭缝确保可移动块的移动程度。细长的板使得可移动块和固定块之间的相对位移。头元件安装在可移动块的后端表面上。非磁性层的厚度对应于头元件的间隙长度。基于非磁性层的沉积可以容易地控制头元件的间隙长度。可以以相对便利的方式减小非磁性层的厚度，使得头元件的间隙长度可以容易地最小化。

摘要： A head slider includes a front rail having an air bearing surface and a step surface lower than the air bearing surface, provided on a disk faced surface in the vicinity of an air inflow end, a transducer provided in the vicinity of an air outflow end, and a groove for generating a negative pressure by expanding air once compressed by the front rail. The head slider further includes a piezoelectric actuator mounted on a head slider back surface on the opposite side of the disk faced surface excluding the vicinity of the air outflow end. By the piezoelectric actuator, the front rail and the neighboring portion are deformed in the direction toward the recording medium or away from the recording medium, and the positive pressure generated at the air bearing surface is regulated, whereby the floating amount of the head slider can be regulated.

摘要： A receiver receives an acoustic wave in an atmospheric pressure measuring apparatus. Since a variation in the intensity of an acoustic wave reflects a variation in the atmospheric pressure, the atmospheric pressure can be measured based on the intensity of the acoustic wave received at the receiver. The atmospheric pressure can in this manner easily be measured with a simplified structure.

摘要： A head suspension supporting a head at the tip end is allowed to swing at the tip end of a carriage in a recording disk drive. A microactuator is interposed between the head suspension and the carriage. A resistor is connected to the microactuator in serial. The microactuator is allowed to function as a capacitance. A combination of the microactuator and the resistor enables establishment of a so-called low pass filter. A high frequency noise involuntarily introduced in the driving voltage for the microactuator can be eliminated or removed from the driving voltage. Elimination of the high frequency noise enables a reliable prevention of the mechanical or physical resonance or vibration in the head suspension. A tracking action of the head related to a target recording track can reliably be stabilized.

The communication chamber includes: a positive pressure control valve configured to open, and send evaporated fuel, which occurs inside the fuel tank, to an evaporated fuel reservoir via the communication chamber and the charge path when the internal pressure of the fuel tank becomes equal to or greater than a predetermined pressure; and a negative pressure control valve configured to open, and send air from the evaporated fuel reservoir to the fuel tank via the communication chamber and the charge path when the internal pressure of the fuel tank becomes equal to or less than the predetermined pressure. In addition, a key cylinder sets the negative pressure control valve open upon inserting a key into the key cylinder.

摘要： According to one embodiment, in a disk drive, a voice coil motor is controlled to cause a head to minutely vibrate in a radial direction on a track of a disk. When the voice coil motor vibrates the head in the radial direction of the disk, frictional force occurring between the disk and the head is calculated based on the driving force of the voice coil motor generated to vibrate and detected positional information, thereby measuring frictional characteristics.

摘要： A flying head slider includes a write head element and a read head element mounted on the slider body. A first transformable actuator serves to protrude the write head element toward a recording medium. A second transformable actuator serves to protrude the read head element toward the recording medium. The first and second transformable actuators can separately be controlled. The amount of protrusion can thus be individually controlled for the write head element and the read head element. The flying height can individually be set above the surface of the recording medium for the write head element and the read head element. Such an adjustment of the flying height enables the write head element and the read head element to simultaneously get closest to the recording medium.

摘要： Lubricant on a rotating recording medium can attach to a slider, particularly on the pad formed in the proximity of the trailing edge. In the slider of this invention, lubricant is not accumulated in the vicinity of the trailing edge and can be drawn to the trailing edge and dispersed constantly. The head slider includes a center pad formed on an air bearing surface in the vicinity of the center of a trailing edge of the slider. A trailing pad is formed so as to bridge a trailing edge of the center pad and the trailing edge of the slider. The trailing pad is formed lower than a highest surface of the center pad and higher than a lowest surface of the slider.

摘要： A head is moved in a lateral direction on the boundary between a separation track and a recording track on a recording medium. The separation track isolates the adjacent recording tracks from each other. A variation is detected in the output supplied from the head based on the recording track. Positional information indicating the position of the head is generated based on the variation. The output supplied from the head varies in response to the movement in the lateral direction, namely the elapsed time. The positional information can thus be generated based on the variation in the output. The generated positional information contributes to an accurate positioning in a facilitated manner. Moreover, information required to position the head can be omitted from the recording medium. The processes can be simplified in the production of the recording medium. The operation time can thus be shortened.
