    Abstract: A disk drive includes a disk drive base, a disk, and a head stack assembly rotatably coupled to the base adjacent the disk surface of the disk. The disk drive includes an airflow channeling enclosure. The enclosure includes an airflow inlet disposed downstream of the head stack assembly and configured to receive the disk rotation induced airflow therethrough. The enclosure further includes an airflow channel extending along the disk surface from the airflow inlet. The enclosure further includes an outer wall extending along the disk surface from the airflow inlet and defining the airflow channel radially interior to the outer wall. The enclosure further includes an airflow outlet disposed upstream of the head stack assembly extending from the outer wall and the channel opposite the airflow inlet for modifying the disk rotation induced airflow passing from the channel.

    Abstract: The invention discloses process for enhancing squeaky feel by reducing or eliminating surfactant micelles on dilution. The present invention focuses, for example, on the relationship between counter-ion (e.g., cation, preferably salt cation) and surfactant. Specifically, it has been found that enhancing the precipitation of counter-ion-surfactant complex helps reduce surfactant micellar concentration, reduce surface tension and lead to enhanced “squeaky” feel. The precipitation can in turn be promoted by enhancing surfactant counter-ion interaction, e.g., by increasing sensitivity of surfactant to counter-ion (e.g., by using long chain length hydrophobe group), and/or by preformulating additional counter-ion into the surfactant solution. Micellar structure can also be reduced or eliminated by co-blending of surfactant, using co-solvent and/or using surfactants of lower Krafft point.

    CPC classification number: H01L43/12

    Abstract: Following CMP, a magnetic tunnel junction stack may protrude through the oxide that surrounds it, making it susceptible to possible shorting to its sidewalls. The present invention overcomes this problem by depositing silicon nitride spacers on these sidewalls prior to oxide deposition and CMP. So, even though the stack may protrude through the top surface of the oxide after CMP, the spacers serve to prevent possible later shorting to the stack.
