摘要:
The present invention provides a self lubricating magnetic recording system that delivers lubricant molecules from a gas phase to the surface of recording media at a sufficient rate to cover the exposed media before it can interact with the writing transducer. The environment around the media surface includes lubricant vapor, and when the lubricant film is removed from the disc surface, e.g., upon heating of the medium, it is replaced by adsorption from the surrounding vapor. The lubricant is thus replenished by delivering lubricant from the vapor phase.

A ferroelectric transducer for use with a ferroelectric storage medium includes a read electrode. The read electrode emits a current when a polarity orientation of the read electrode is opposite a polarity orientation of a ferroelectric domain on the storage medium.

A sensing contact probe includes a beam support and a probe. The probe has a bent beam body that extends from the beam support to a probe tip face that has a position and faces in an angular direction. The bent beam body has first and second beam layers bonded together and have differing residual stresses that bend the beam body. A stress relief region is formed in the bent beam body. The stress relief region has an adjusted stress property that adjusts the bending to control the probe tip face position and angular direction.

A lubricant layer for a magnetic recording medium may include a perfluoropolyether having monomer units and end groups selected to provide high thermal stability and good reliability.
摘要:
A data storage device comprising a storage medium having a recordable surface, a transducing head having a bearing surface positioned adjacent to the recordable surface of the storage medium, and at least one compound disposed between the recordable surface and the bearing surface, the at least one compound comprising at least one functional group that imparts corrosion resistance and at least one functional group that imparts lubricating properties.
摘要:
A magnetic recording medium including a solid lubricant film containing a plasma-enhanced chemical vapor deposited perfluoropolyether is disclosed. Preferably, the solid lubricant is formed in the presence of oxygen and longer fluorocarbon chain to form perfluoropolyether, thereby enhancing the chain flexibility perfluoropolyether and in the presence of a hydrocarbon to stabilize the process, thereby allowing process control.
