Abstract

A disc drive includes a housing surrounding a voice coil in a voice coil cavity, and a disc in a disc cavity. The disc has data tracks and an outer diameter. The disc rotates to induce an airflow along the outer diameter. The voice coil actuates an actuator arm in the disc cavity to access the data tracks. An air dam is in the disc cavity upstream of the actuator arm. The airflow includes a straight line tangent airflow portion along a straight edge of a shroud that is free of obstructions and upstream of the air dam. The straight line airflow portion extends from an arc airflow portion around the outer diameter to the voice coil cavity along a straight line path tangent to the outer diameter.
