Abstract
The present invention is an after-assembly shroud in a magnetic disk drive. The shroud of the present invention is attached to a housing after assembly of the disk drive and actuator near the circumferential edge of the disk. The disk is attached to the housing of a magnetic disk drive so that it is rotatable with respect to the housing. The invention relates to a fabrication method for the magnetic disk drive. The assembly method is adapted for attaching the shroud to the housing of the disk drive after assembly and is performed according to novel assembly sequence. The shroud of the present invention reduces disk flutter due to turbulent air flow, and track positioning precision can be enhanced.
