摘要： A disk apparatus includes a ramp which holds a tip end of an arm at a position away from a disk, and a slit shroud having an airflow control plate. A side surface of the airflow control plate is opposed to a side surface of the disk, the airflow control plate spreads to a position where the airflow control plate is superposed on the tip end of the arm held by the ramp. The airflow control plate has the same thickness as that of the disk, and is flush with the disk 12.

摘要： First and second shroud surfaces are defined along an imaginary cylinder coaxial to a recording disk. A shroud plate is located between the first and second shroud surfaces. Airflow flows outward along the surface of the rotating recording disk based on the centrifugal force. The shroud plate serves to establish the continuity of the first and second shroud surfaces. The first and second shroud surfaces and the shroud plate serve to reliably suppress turbulence of the airflow. Vibration of the recording disk is suppressed than ever. An inflow opening is located in a space between the first and second shroud surfaces. The rectifier plate is located downstream of the inflow opening. The rectifier plate serves to direct the airflow flowing along the first shroud surface to the inflow opening. A larger amount of airflow can be introduced into the inflow opening. A dust catcher receives airflow of a sufficient amount.

摘要： A magnetic disk device includes a swing-type head actuator which is driven by a voice coil motor. The voice coil motor is cooled by an airflow generated when a magnetic disk accommodated in a disk accommodating unit of an enclosure is rotated by a spindle motor. An airflow dividing member provided on an inner wall or a base of an actuator accommodating unit divides the airflow generated by the rotation of the disk and passing along the inner wall. The divided airflow is introduced to a coil part of the voice coil motor, and cools the coil, without sacrificing the dust purge performance.
