Abstract
The present invention generally relates to a disk drive and methods for operating the same. A venting assembly of this disk drive generally includes a slider having an air bearing surface system for generating positive pressure to urge the slider away from a data storage disk, and a suction cavity for generating negative pressure to urge the slider toward the surface of the disk. The slider of the venting assembly also generally includes a first venting hole extending through the slider within the suction cavity. A first valve of the venting assembly is generally associated with the first venting hole to at least assist in controlling airflow through the same. Contact between a load beam of the venting assembly and a corresponding load/unload ramp of the disk drive during unloading of the slider generally tends to open the first valve and substantially dissipate the negative pressure within the suction cavity.
