摘要： A magnetic head device has a magnetic head slider by means of which information is recorded in and read from a magnetic recording medium. The magnetic head slider is supported by a supporting structure having an internal cavity, an opening formed in a portion of the structure where the magnetic head slider faces the magnetic recording medium and communicating with the internal cavity, and a gas passage through which the gas introduced into the internal cavity through the opening is discharged to the exterior of the internal cavity. With this arrangement, the pressure acting on the back surface of the magnetic head slider is adjusted to keep the slider afloat, while removing dust suspended in the gas around the recording medium and the supporting structure.

摘要： A stage comprises a linear guide rail (2) for guiding a movable table (4), a driven bar (12), a linear drive actuator in contact with the driven bar (12) to transmit driving force to the driven bar (12), and parallel plate springs (30) for holding opposite ends of the driven bar (12). A drive transmitting surface of the linear drive actuator is provided so as to be separated from the movable table (4), and this prevents the accuracy of positioning from being reduced. Also, the parallel springs (30) reduce deforming forces applied to sections supporting the driven bar (12), and this prevents the driven bar from being damaged. The configuration makes the stage highly accurate and highly reliable.
