摘要： PROBLEM TO BE SOLVED: To provide a recording disk drive apparatus which can contribute largely to suppression of disturbance of an air stream and ramp member which is useful largely for realizing such recording disk drive apparatus.
SOLUTION: The recording disk drive apparatus 11 is connected to a supporting shaft 23 freely rotatably and is provided with a head actuator 21 supporting a head slider 26 at a tip. A flow straightening plate 42 prescribes an edge 44 on a circular arc 45 plotted with an equal distance from the supporting shaft 23. The flow straightening plate 42 is arranged at the outside of a circular arc 43 plotted at a tip of the head actuator 21. Thus, the flow straightening plate 42 is arranged at a down stream of the head slider 26. Thus, distance between the flow straightening plate 42 and the head slider 26 is held constant independently of a position of the head slider 26. Disturbance of an air stream can be suppressed surely at the down stream of the head slider 26 during rotation of a recording disk 13.
