Disk drive including an airflow blocker with a planar portion extending from a blocker arm portion
View Patent ↗A disk drive includes a disk drive base and 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 head stack assembly including an actuator arm disposed adjacent the disk surface. The disk drive further includes an airflow blocker coupled to the disk drive base for mitigation of disk rotation induced airflow upon the head stack assembly. The airflow blocker includes a blocker body disposed adjacent the outer disk edge attached to the disk drive base. The airflow blocker further includes a blocker arm portion extending from the blocker body along the disk surface. The airflow blocker further includes a planar portion extending from the blocker arm portion disposed along the actuator arm when the actuator arm is rotated over the disk surface.
1. A disk drive comprising:
a disk drive base;
at least one rotatable disk including a disk planar surface extending to an outer disk edge;
a head stack assembly rotatably attached to the disk drive base in operable communication with the disk, the head stack assembly including an actuator arm disposed adjacent the disk surface; and
an airflow blocker coupled to the disk drive base for mitigation of disk rotation induced airflow upon the head stack assembly, the airflow blocker comprising;
a blocker body disposed adjacent the outer disk edge attached to the disk drive base;
a blocker arm portion extending from the blocker body over the disk surface; and
a planar portion extending from the blocker arm portion disposed across the actuator arm and over the disk surface when the actuator arm is rotated over the disk surface.
2. The disk drive of claim 1 wherein the blocker arm portion is disposed upstream of the head stack assembly.
3. The disk drive of claim 1 wherein the disk surface is a first disk surface and the disk includes a second disk surface disposed opposite the first disk surface, the actuator arm is a first actuator arm and the head stack assembly includes a second actuator arm disposed adjacent the second disk surface, the blocker arm portion is a first blocker arm portion and the airflow blocker includes a second blocker arm portion extending from the blocker body over the second disk surface, the planar portion is a first planar portion and the airflow blocker includes a second planar portion extending from the second blocker arm portion across the second actuator arm and over the disk surface when the second actuator arm is rotated over the second disk surface.
4. The disk drive of claim 3 wherein the first planar portion is attached to the second planar portion adjacent the outer disk edge.
5. The disk drive of claim 1 wherein the planar portion is disposed between the actuator arm and the disk surface when the actuator arm is rotated over the disk surface.
6. The disk drive of claim 1 wherein the actuator arm is disposed between the planar portion and the disk surface when the actuator arm is rotated over the disk surface.
7. The disk drive claim 1 wherein the planar portion is an inner planar portion, the airflow blocker further includes an outer planar portion extending from the blocker arm portion with the actuator arm being disposed between the outer planar portion and the inner planar portion when the actuator is rotated over the disk surface.
