Disk drive with airflow channeling enclosure

A disk drive comprising:

• a disk drive base;
• a disk rotatably coupled to the disk drive base, the disk including a disk surface and defining an axis of rotation;
• a head stack assembly rotatably coupled to the disk drive base adjacent the disk surface;
• and
• an airflow channeling enclosure partially coextensive from the center to the radial boundary of the disk surface, the airflow channeling enclosure including:
• a first plate,
• an airflow inlet disposed downstream of the head stack assembly with respect to disk rotation induced airflow and configured to receive the disk rotation induced airflow therethrough;
• an airflow channel extending along the disk surface from the airflow inlet;
• an outer wall extending along the disk surface from the airflow inlet and defining the airflow channel radially interior to the outer wall with respect to the disk;
• and
• an airflow outlet disposed upstream of the head stack assembly extending from the outer wall an the airflow channel opposite the airflow inlet for modifying the disk rotation induced airflow passing from the airflow channel.
