摘要： The positioning accuracy of a magnetic head decreases due to vibrations in the in-plane rotation mode of an HDD, which are caused by couple or disturbance occurring in seek operation, due to vibrations in the thrust mode, and the conical mode, of the spindle, which are caused by disturbance, and due to vibrations in the case thrust mode, the spindle fall mode, and the like. In one embodiment, an elastic support member includes a pillar-shaped part. The elastic support member is provided with a recess on a surface opposite to a corner of a base, and longitudinal fin projections on the upper and lower sides with respect to the recess. The base is provided at its corner with a horizontal fin that is parallel to a disk surface. The horizontal fin is inserted into the recess of the elastic support member. The longitudinal fin projections come into contact with the base, and control basic vibrational characteristics on both the upper and lower sides with respect to the horizontal fin. The pillar-shaped part is provided with a zigzag-shaped part so that the pillar-shaped part may come into contact with a frame.

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 disc unit which can restrain occurrence of flutter so as to countermeasure such a problem that the larger the rotational speed of discs, the higher the flutter, causing heat positioning errors, in order that the high rotational speed and high positioning accuracy are consistent with each other. Discs are surrounded along their outer peripheries by a shroud (outer wall) while a gap between end faces of the discs and the shroud is decreased to a predetermined distance, thereby to eliminate air pressure differential between opposite surfaces of each of the discs in order to reduce flutter.

摘要： Return channels 45a, 45b, 45c, and 50 are formed to guide air flowing through a clearance between a magnetic disk (11) and a shroud (41) so that the air flows behind a voice coil motor, bypasses a loading/unloading mechanism (31) and flows toward a region on the lower side of the loading/unloading mechanism 31 with respect to the rotating direction of the magnetic disk (11). Thus, production of turbulent flow in the vicinity of the loading/unloading mechanism 31 is controlled. Fluttering of the magnetic disk (11) can be controlled by placing a filter 60 in one of the return channels.
