Embodiment Construction

[0012] The following description is of what is presently believed to be the best mode for carrying out the invention. This description is made for the purpose of explaining the basic principles of the invention and is not intended to limit the inventive concepts claimed herein.

[0013] now refer to figure 1 , shows a hard disk drive 100 embodying the present invention. Such as figure 1 As shown, at least one rotatable disk 112 is supported on a spindle 114 and rotated by a hard drive motor 118 . Magnetic recording on each disk is in the form of a circular pattern of concentric data tracks (not shown) on disk 112 .

[0014] At least one slider 113 is disposed adjacent to the magnetic disk 112 , and each slider 113 supports one or more magnetic head assemblies 121 . As the disk rotates, the slider 113 moves radially in and out over the disk surface 122 so that the head assembly 121 can access the different tracks of the disk on which desired data is written. Each slider 11...

Abstract

Oxygen scavenger for use in a hard disk drive. The oxygen scavenger removes oxygen from an interior of a hard disk drive to prevent corrosion of corrodible materials in magnetic media or magnetic heads. The oxygen scavenger is incorporated into a film so that it uses a limited physical space within an interior of the hard disk drive. The hard disk drive is either permeable to the outside environment or sealed so that gases from the outside environment are unable to enter the interior of the hard disk drive.

Description

technical field [0001] The present invention relates to a hard disk drive. Background technique [0002] Hard disk drives and their components are made from corrosion-prone metallic materials such as cobalt and iron. Head and media corrosion is a particular challenge in hard disk drive technology. Recently, perpendicular recording techniques have been implemented, drawing more attention to corrosion. In addition, the push to higher areal densities requires reducing the thickness of the overburden on the heads and media, making them more susceptible to corrosion. Even if the media or head has adequate protective coating coverage during its early life, slow wear over the operating life of the head / disk contact can cause the protective coating to be removed from portions of the head or media. Removal of this protective layer can lead to corrosion and failure of the hard drive. [0003] Several schemes for preventing corrosion of drives have been proposed. US Patent No. 676...
