Method for controlling airflow through a disc file spindle

A disk drive apparatus comprising:

• a disk container;
• at least one disk within said disk container;
• a hub assembly further comprising:
• a spindle having a first end and a second end, said spindle attached to said disk container, said spindle including an internal air passage and including a first opening near said first end and a second opening near said second end, both of said first and second openings in fluid communication with said internal air passage and in fluid communication with said disk container;
• and
• a hub attached to said spindle so that the hub rotates about the spindle assembly having said
• at least one disk attached to said hub of said hub assembly;
• and
• an actuator assembly attached to said disk container, said actuator assembly further comprising:
• an actuator shaft attached to said disk container;
• an arm assembly attached to said actuator shaft so that the arm assembly rotates about said actuator shaft;
• and
• a read/write head attached to said arm assembly so that the read/write head is passed over the surface of the disk during rotation.
