An apparatus and associated method for enclosing an environment-sensitive component. An enclosure separates an interior environment inside the enclosure from an external environment outside the enclosure. The enclosure has an environmental control system that captures a contaminant from the internal environment to a filter via a first diffusion path, and captures the contaminant from the external environment to the same filter via a different second diffusion path, the diffusion paths providing substantially different flow resistances to fluids carrying the contaminants to the filter via the respective diffusion paths.

Dual diffusion path filtering

Certain exemplary aspects of the present disclosure are directed towards an apparatus including a base deck, a plurality of storage mediums (e.g., discs) and a plurality of disc separator plates. The base deck includes a sidewall forming a cavity to house the storage medium, with slots in the sidewall in which each disc separator plate extends. The disc separator plates extend into spaces between peripheral ends of adjacent ones of the storage medium. This arrangement can be used to provide rigid coupling of the separator plates, which can mitigate issues relating to vibration or shock. Further, air flow can be mitigated in this regard, such as to reduce effects upon a magnetoresistive transducer that reads data from the storage mediums.

Apparatus with disc separator plates

A data storage system is provided. The data storage system has an enclosure with at least one disc rotating about a central axis and having a corresponding airflow. The airflow is subject to contamination by particles. A particle deposition surface is located inside the enclosure of the data storage system having a surface roughness of at least 30-microns. The particles contaminating the airflow are deposited on the particle deposition surface.

Method of removing particles from an airflow and a data storage system including the same

An apparatus and method for reducing structural vibrations in a disc drive that incorporates a fusible alloy. A fusible alloy portion is constrained between a first and second structural alloy portion through conventional lamination techniques. A fusible alloy can be incorporated into any structural component of the disc drive, including a base plate and an information storage disc. Fusible alloys incorporated into the disc drive absorb energy transmitted by vibrations through anelastic deformation, i.e., through dislocation motion. Suitable fusible alloy materials may include but are not limited to: Lead-Tin, Indium-Tin and Indium-Bismuth.
