PURPOSE:To prevent a disk from fluttering due to a revolving airflow by mounting at least one straightening vane between the disks disposed at a fixed interval and having their individual independent airflow paths. CONSTITUTION:A hub 15 fitted onto a spindle 14 is laminated alternately with a disk medium 16 and a clamp ring 17. Then, at least one of the straightening vanes 23 supported by a straightening vane supporting base 24 is disposed in the middle of the interval of the disk medium 16. In addition, the hub 15 and the clamp ring 17 are formed of opening 26 and 27 for an airflow. Now, when the spindle 14 is rotated, the air around the disk is moved away by a centrifugal force to cause a negative pressure on the inner side of the disk, so that new air is sucked from the opening 26 and 27 to generate an airflow. However, since the independent airflow is created at every straightening vane, the disk is prevented from fluttering due to an airflow.
