An airflow control device in a disc drive to remove turbulence from air currents used to aerodynamically support a read/write head adjacent a rotatable disc. The direction of disc rotation is such that a given point on the disc reaches the head prior to reaching an arm used to support the head over a complete revolution of the disc. The airflow control device is placed upstream from the head and forms a channel within which the head moves across the disc. The airflow control device includes a diverter member upstream from the head and a screen member which extends over the head. During operation, air currents impinge upon the diverter member and most of these currents are diverted away from the head. A small portion of the air currents passes through a gap between the diverter member and the disc and flows on to the head to support the head.

An air current diverting apparatus for a data storage device having a rotating data storage medium in operable relation with an actuator assembly reading data from and writing data to the data storage medium. The air current diverting apparatus has an aerodynamic shroud comprising a base having a first end attachable to the actuator assembly, an upstream surface extending upstream of the actuator assembly, and a downstream surface extending downstream of the actuator assembly and substantially non-parallel to the upstream surface.

The present invention is directed to a disc heater for use with a spin-stand. The disc heater is adapted to heat a disc that is mounted to a spindle of the spin-stand. The disc heater includes a heater support, a heater, and a controller. The heater support is couplable adjacent the spindle and the disc and is adapted to support the heater near a surface of the disc. The heater produces heat that raises at least a surface of the disc to a temperature that simulates an operating temperature of a disc drive. The controller is electrically coupled to the heater and controls the heat produced by the heater. The spin-stand is adapted to perform various tests on the transducing head. Additional tests, such as accelerated aging studies, can also be performed on the disc.
