摘要： A method of detecting a gap between a head and a recording medium in an information-recording/reproducing apparatus that uses the head to record and reproduce information in and from the recording medium. In the method, the gap between the head and the recording medium is alternately increased and decreased, thereby gradually reducing the gap between the head and the recording medium. A detection signal is detected from which to determine a contact between the head or a slider supporting the head and the recording medium. When it is determined that the head or the slider has contacted the recording medium, the head is stopped and moved away from the recording medium to a prescribed position, and data representing a distance the head has moved to contact the recoding medium is acquired.

摘要： A head slider in a magnetic disk drive wherein provisions are made to facilitate the evaporation of lubricant adhering to the slider and thereby substantially reduce the chance of the fly height of the slider becoming unstable due to a lubricant drop. A head element, a heat generating element, and a multilayered heat conducting structure formed from multiple layers stacked along a longitudinal direction of the slider, with at least one layer extending up to portions near both lateral sides of the slider, are embedded into a nonmagnetic insulating layer formed in an air exit end portion of the slider. The heat generated by the heat generating element is efficiently conducted throughout the nonmagnetic insulating layer to heat the entire structure of the nonmagnetic insulating layer. As a result, the lubricant adhering to any portion of the nonmagnetic insulating layer is efficiently heated, causing the lubricant to evaporate or flow.

摘要： An AC power source is connected to a write coil mounted on a head slider for determination of contact of a head slider with a storage medium. The AC power source outputs the alternating current having a specific frequency. A measuring circuit measures a sequence of indices for the alternating current supplied to the write coil. A component corresponding to the specific frequency is extracted from the sequence of the indices. This serves to eliminate components corresponding to frequencies other than the specific frequency, namely noise. A detecting circuit detects contact between the head slider and the storage medium based on a change in the amplitude of the sequence appearing at the specific frequency. The contact can thus reliably be detected between the head slider and the storage medium.

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 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 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.
