| 20090116141 | APPARATUS, SYSTEM ,AND METHOD FOR CONTROLLING OUT-GASSING AND HUMIDITY IN A CLOSED SPACE-CONSTRAINED ENVIRONMENT - An apparatus, system, and method are disclosed for controlling out-gassing and humidity in a closed space-constrained environment. In particular, an environment control device is disclosed which is made using thermoforming techniques such that the walls of the device are much thinner than other conventional devices. This allows for the device to be used in space-constrained environment while still providing a sufficient amount of absorber material such as a desiccant. The apparatus includes a base made up of a thin flexible plastic film thermoformed to create a cavity having at least one wall, the cavity having an opening on one side.

| 20100266754 | SYSTEMS AND METHODS FOR PROCESSING A MAGNETIC DISK - A system and associated methods are described for preparing a magnetic disk for installation within a disk drive system. For example, a polyfunctional lubricant may be mixed with a chemical agent to esterify the polyfunctional lubricant and cap hydroxyl groups of the polyfunctional lubricant. The magnetic disk may then be dip coated with the polyfunctional lubricant and chemical agent mixture. A polishing system then polishes the magnetic disk via an abrasive polishing tape after dip coating the magnetic disk. A portion of the chemical agent is then removed from the magnetic disk to bond a portion of the lubricant to the magnetic disk to prevent the lubricant from interfering with a read/write head when installed within a disk drive system. | 10-21-2010 |
| 20110141628 | LAMINATED MONOLITHIC POLYMER FILM DESICCANTS FOR MAGNETIC STORAGE DEVICES - A desiccant device that emits no contamination and is therefore suitable for use in an electronic device such as a magnetic disk drive system. The desiccant device includes a pouch formed of a laminate layer. The laminate layer includes a thin, non-permeable monolithic membrane laminated to a porous media. The thin, non-permeable monolithic membrane is thin enough to allow a desired vapor to pass there-through by molecular diffusion, but does not include any voids, pores or holes that would allow gas, liquid or solid to permeate there-through. Since the permeable membrane only passes vapor by molecular diffusion, it prohibits any dust fibers or other contamination from emitting from the desiccant device and thereby prevents contamination of the electronic device such as the disk drive. | 06-16-2011 |

| 20110090592 | Integrated Upstream Spoiler and Particle Filter in a Hard-Disk Drive (HDD) - Approaches for integrating an upstream spoiler with a particle filter in a hard-disk drive (HDD). According to an approach, a single part may comprise an upstream spoiler and an opening. The single part has a structure which enables an airborne particle filter to be positioned over or within the opening. The airborne particle filter, which covers the opening, has a curvature that follows the curvature of a shroud. When the upstream spoiler diverts a flow of air, which circulates within the enclosure when the magnetic-recording disk is rotating, from the magnetic-recording head, the upstream spoiler creates an area of relatively greater pressure. Air in the area of greater pressure flows through the airborne particle filter to an area of relatively lesser pressure, thereby removing airborne particles within the enclosure of the HDD. Alternately, the airborne particle filter may be positioned within slits present in the shroud and the upstream spoiler. | 04-21-2011 |
