摘要： A disk drive includes a drive housing, a storage disk, a head suspension assembly, an actuator assembly and a controller. The storage disk has a disk surface including a data region that stores data. In one embodiment, the head suspension assembly includes a slider and an attitude adjuster. The slider has an inner side edge, an outer side edge and a data transducer. The attitude adjuster can adjust a roll attitude and/or a pitch attitude of the slider relative to the disk surface. The slider moves between a first position wherein the data transducer is not positioned directly over the data region and a second position wherein the data transducer is positioned directly over the data region during one of a load operation and an unload operation. The controller controls an electrical signal to the attitude adjuster during one of the load operation and the unload operation to dynamically adjust the attitude of the slider. The attitude adjuster can include one or more piezoelectric elements that expand and/or contract to adjust the orientation of the slider relative to the storage disk.

摘要： An X-ray tube has a rotating anode and a plain bearing for mounting the rotating anode in a vacuum housing. The plain bearing has an inner bearing part that is stationary in relation to the vacuum housing, and a rotating outer bearing part that is connected with the rotating anode and that rotates with this anode relative to the vacuum housing during the operation of the X-ray tube. Between these inner and outer bearing parts there is a bearing gap filled with lubricant at least in the region provided for the transmission of force. The inner bearing part, which extends through the outer bearing part, is connected to the vacuum housing at both ends. The bearing gap has the same outer diameter at each of its two ends.
