Cleaning a recording head slider in-drive during operation is accomplished by periodically performing a series of full stroke seek operations, whereby liquid contaminants that may have migrated to the head slider are flung from the slider and liquid from the disk surface may be adsorbed onto the slider for removal by way of flinging. Consequently, head-disk spacing may be stabilized and data write operations improved. Furthermore, the series of full stroke seek operations may be performed at predetermined intervals, and for a predetermined period of time. However, the series may be interrupted by a client request, and continued thereafter, so as not to affect the operational status of the recording system.

A method and apparatus for regulating the concentration of a vapor within a hard drive are provided. In one embodiment, the method may include providing a source chemical of a vapor in a first cavity formed within a first object, providing an absorptive chemical which absorbs the vapor in a second cavity formed within the first object, and providing a third cavity formed by a hard drive housing of the hard drive. A first conductance path having a first conductance connects the first cavity to the third cavity, a second conductance path having a second conductance connects the second cavity to the third cavity, and the first conductance and the second conductance maintain a partial pressure level of the vapor within the third cavity.
