Abstract:
1. A recording apparatus comprising: at least one disk fixed to a rotation shaft; a head movable on a surface of said disk to write information onto the disk or read the information recorded on the disk; an arm supporting the head; an actuator for moving the arm; a shroud section of arc-shape extending around a part of an outer periphery of the disk other than the other part thereof facing to a movable range of the arm; a housing receiving therein said disk, said arm and said actuator; and a cover covering said housing, wherein a first convex section is provided to reduce a size of a gap between said disk surface and said cover or between said disk surface and said housing in an area outside an area in which the arm traverses on said disk, in comparison with the area in which the arm traverses, a second convex section is provided on a part of the first convex section to further reduce the size of the gap between the disk surface and said cover or between said disk surface and said housing in comparison with the first convex section, and said second convex section has an upstream part in a rotational direction of said disk, and the upstream part is inclined in the rotational direction with respect to a straight line connecting a rotational center of said disk and a front end of said a second convex section on an upstream side in the rotational direction.
