Abstract
A method and system of controlling contamination within an HDD with a surface modified MCM 41/48 material. The method includes encasing the hard disk drive and a mesoporous material in an enclosure of the hard disk drive, wherein the mesoporous material sorbs contaminants within said enclosure.
Claims17
Hard disk drive comprising hard disk drive contamination control, said disk device comprising:
- an enclosure of said hard disk drive;
- and
- a mesoporous material disposed within said enclosure, wherein said mesoporous material sorbs contaminants within said enclosure and wherein said mesoporous material has substantially uniform pore size across an outer surface of said mesoporous material.
A method of manufacturing a hard disk drive with contamination control, said method comprising:
- encasing said hard disk drive and a mesoporous material in an enclosure of said hard disk drive, wherein said mesoporous material sorbs contaminants within said enclosure and wherein said mesoporous material has substantially uniform pore size across an outer surface of said mesoporous material.
A method of enabling low fly height in a hard disk drive, said method comprising:
- surface modifying MCM 41/48 that is initially hydrophilic in nature to hydrophobic in nature, wherein said surface is modified by Me3SiCl;
- and
- encasing said hard disk drive and said surface modified MCM 41/48 in an enclosure, wherein said surface modified MCM 41/48 adsorbs siloxanes within said enclosure to prevent hard disk drive failure.
