Abstract
A data storage device for storing and accessing data includes a motor and at least one movable medium coupled to the motor. The motor is capable of moving the medium and thereby generating turbulent airflow. The data storage device further includes at least one surface having at least two grooves. The two grooves extend along a groove axis that is substantially perpendicular to a mean airflow direction and are capable of reducing the interaction between the surface and a turbulent airflow generated by the medium.
Claims23
A data storage device for storing and accessing data, the storage device comprising:
- a motor;
- at least one movable medium coupled to the motor and capable of being moved by the motor and thereby generating a turbulent airflow;
- and
- at least one internal surface comprising at least two grooves having a groove axis oriented substantially perpendicular to a mean airflow direction so as to reduce interaction between the internal surface and a turbulent airflow generated by the medium.
A surface for a component in a disc drive, the surface comprising;
- a first groove having a groove axis that is substantially perpendicular to a direction of expected mean air flow;
- and
- a second groove proximate the first groove and having a groove axis that is substantially perpendicular to the expected mean air flow such that the first and second grooves cooperate to reduce interaction between vortices in the air flow and the surface.
A disc drive for storing and accessing data, the disc drive comprising:
- a moving medium that generates an airflow having eddies in the disc drive;
- and
- excitation reduction means defining a surface in the disc drive for reducing the excitation of the surface by causing eddies in the airflow to be moved away from the surface.
