Abstract
A magnetic disk drive having a layer of ZTMD raffinate coated within a housing of the disk drive to trap debris in order to prevent contamination related failure of the disk drive. The ZTMD raffinate can be applied to the inside of the housing of the disk drive, such as to side walls of the housing and or the cover of the housing. The ZTMD raffinate can also be applied to a filter structure within the housing in order improve the performance of the filter structure and prevent contamination collected thereon from becoming dislodged.
Claims24
A magnetic disk drive, comprising:
- a housing;
- a magnetic disk mounted within the housing;
- a suspension arm pivotally mounted within the housing;
- a slider connected with the suspension arm for movement adjacent to a surface of the disk;
- and
- a layer of viscous sticky, viscous material applied to at least a portion of the housing, the viscous sticky material being a bi-product of manufacturing a ZTMD lubricant.
