Abstract
A sickle-shaped disk drive spoiler for reducing turbulence of airflow in a hard disk drive is provided. The sickle-shaped spoiler is configured to direct airflow generated by a rotating disk and includes a tapered first end portion configured to direct the airflow toward the inner diameter of the disk and to reduce the airflow on the side of the disk opposing the spoiler.
Claims22
A sickle-shaped disk drive spoiler configured to direct airflow generated by a rotating disk comprising an inner diameter and an outer diameter, said spoiler comprising:
- a tapered first end portion configured to direct airflow towards said inner diameter;
- and
- a second end portion;
- wherein said tapered first end portion and said second end portion are configured to reduce airflow on the side of the disk opposing said disk drive spoiler;
- and
- at least one attachment point configured to mount said sickle-shaped disk drive spoiler using a force from a distortion of said sickle-shaped disk drive spoiler.
A hard disk drive comprising:
- a housing;
- a disk pack mounted to the housing and having a plurality of disks that are rotatable relative to the housing, the disk pack defining an axis of rotation and a radial direction relative to the axis, said disks comprising an inner diameter and an outer diameter;
- an actuator mounted to the housing and being movable relative to the disk pack, the actuator having a plurality of heads for reading data from and writing data to the disks;
- and
- a plurality of spoilers, at least one spoiler sickle-shaped and comprising:
- a tapered first end portion configured to direct airflow towards said inner diameter;
- and
- a second end portion;
- wherein said tapered first end portion and said second end portion are configured to reduce airflow in an area of a disk opposing said disk drive spoiler;
- and
- at least one attachment point configured to mount said sickle-shaped disk drive spoiler using a force from a distortion of said sickle-shaped disk drive spoiler.
A method for reducing turbulence of airflow in a hard disk drive having a spoiler configured to direct airflow generated by a rotating disk having an inner diameter and an outer diameter, said method comprising:
- providing a sickle-shaped spoiler having
- a tapered first end portion configured to direct airflow towards said inner diameter;
- and
- a second end portion;
- and
- at least one attachment point configured to mount said sickle-shaped disk drive spoiler using a force from a distortion of said sickle-shaped disk drive spoiler
- wherein said tapered first end portion and said second end portion are configured to reduce airflow on the side of the disk opposing said disk drive spoiler.
