Disk drive having airflow suppressor comb with curved extension for reduced disk rotation induced airflow

The present invention relates generally to disk drives, and more particularly to a disk drive having an airflow suppressor comb for reduced disk rotation induced airflow. A disk drive includes a disk drive base. The disk drive further includes at least one rotatable disk including a disk surface extending to an outer disk edge. The disk drive further includes a head stack assembly rotatably attached to the disk drive base in operable communication with the disk. The disk drive further includes an airflow suppressor comb coupled to the disk drive base and stationary relative to the disk drive base during operation of the disk drive. The comb includes a comb body disposed adjacent to the outer disk edge, and at least one tine extending from the comb body along the disk surface for mitigating disk rotation induced airflow upon the head stack assembly adjacent to the disk surface. The comb further includes a curved extension extending along the outer disk edge for mitigating turbulent airflow adjacent the outer disk edge.
