Abstract
A method for manufacturing a magnetic media having an extremely thin lubricant layer on a magnetic media. The thin lubricant layer decreases magnetic spacing to maximize magnetic performance of the magnetic data recording system. The lubricant layer is formed by first depositing a lubricant that includes two different lubricant materials, one bonded and the other non-bonded. After lubricant deposition a burnishing process can be performed, with the lubricant being thick enough for effective burnishing. Then, the disk is exposed to a solvent vapor, which removes most of the lubricant leaving only a very thin layer of the bonded lubricant material.
Claims9
A method for manufacturing a magnetic media for data recording, comprising:
- constructing a magnetic disk;
- depositing a lubricant layer on the magnetic disk, the lubricant layer comprising two different lubricant materials;
- and
- exposing the magnetic disk to a solvent vapor to remove one of the lubricant materials and leaving a layer of the second lubricant material that has a thickness of less than 1 nanometer.
