摘要： A method and an apparatus for analyzing the vibration of the housing of a disk device are disclosed, in which the residual vibration of the housing can be accurately detected for protection against vibrations by determining the transfer function of the rotational acceleration of the housing. The vibration of the housing of the disk device attributable to a head actuator built into a computer or constituting a disk device housed in a locker is detected in such a manner that a random seek current is supplied to the head actuator from an external source, the transfer function of the rotational acceleration of the housing obtained from at least n acceleration sensor mounted on the housing is determined for each frequency, the spectrum of the random seek current supplied to the head actuator is multiplied by the transfer function of the housing, the resulting product is integrated twice thereby to convert the rotational acceleration into a displacement, the converted value of displacement thus obtained is multiplied by the servo follow-up error characteristic of the head actuator thereby to determine the power spectrum of the residual vibration in the frequency domain. The power spectrum is subjected to an inverse Fourier transformation thereby to detect the oscillation of the head with respect to time.

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： 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： 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： 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.
