Abstract
The structure is made such that an aerodynamic latch is provided in an outer portion of a magnetic disc, a front end portion exposed to a wind in the aerodynamic latch is formed to be shorter than an outer peripheral surface of the magnetic disc, and the wind receiving portion of the aerodynamic latch moves an air stream outlet from an end surface of the magnetic disc and a shroud in a direction of forming a flow passage for passing through a portion apart from the magnetic disc. Accordingly, a stable aerodynamic latch drive can be achieved and an air stream within the disc is not disturbed, so that it is possible to reduce a flutter and a consumed electric power.
