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 first shroud and a second shroud are opposed to the peripheral end surface of a recording disk at a certain constant distance. The second shroud is spaced downstream from the first shroud in the direction of the rotation of the recording disk. A shroud plate is opposed to the peripheral end surface of the recording disk at a position between the first and second shrouds. The shroud plate functions as a shroud. The shroud plate serves to suppress turbulence of airflow. Vibration of the recording disk can be suppressed. Moreover, if the shroud plate is designed to extend along a virtual plane perpendicular to the rotation axis of the recording disk, the airflow is prevented from staying between the first and second shrouds. The airflow can effectively be taken out. The airflow can effectively be utilized.

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.

摘要： In a load/unload type disk drive, when a head for reading/writing information on a disk is retracted outside the disk by a swing arm at the time of stopping the operation of the disk drive, a ramp mechanism holds a lift tab provided at the tip of the swing arm, wherein the ramp mechanism comprises a holding member for holding the lift tab and a mounting member for mounting the holding member thereon, the mounting member having a guide capable of adjusting the mounting position. The holding member mounted on the mounting member is tentatively fastened thereto, with provisions made to be able to adjust the position of the thus mounted holding member by moving it along the guide in a direction conforming to the rotational path of the holding member.
