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.

摘要： A magnetic disc unit includes a rotating disc type magnetic disc having an outer periphery, and a carriage arm linked to a head support mechanism for a recording/reproducing head. A base has an outer periphery and mounts the rotating disc type magnetic disc and the carriage arm, and has a side wall with an inner wall surface having an opening for inserting the carriage arm. The inner wall surface of the side wall defines a shroud surrounding the outer periphery of the magnetic disc, except at the opening in the side wall where the shroud is projected inwardly so as to decrease an opening angle of the opening in the side wall. A gap between the outer periphery of the magnetic disc and the shroud is set in a range not less than 0.1 mm but not greater than 0.6 mm.

摘要： A magnetic disk apparatus includes a magnetic disk, a magnetic head slider, a controller for controlling a position of the magnetic head slider, and an load/unload mechanism for loading or unloading the slider to the disk. The disk includes a track and has at least a load zone of a predetermined length in a peripheral direction thereof for performing loading of the magnetic head slider on a surface of the disk utilizing the load/unload mechanism, a specific pattern recorded in front of the load zone in the peripheral direction thereof, and a data zone provided in front of the specific pattern in the peripheral direction thereof. The controller reads out the specific pattern recorded on the disk utilizing the slider, and controls the position of the slider so as to move the slider while avoiding the load zone.
