Abstract
A component of a recording device comprising a magnetic layer, means for improving corrosion resistance of the magnetic layer and a carbon overcoat, and a method of making and using the same are disclosed. The means for improving corrosion resistance of the magnetic layer comprises a sealing layer comprising a refractory metal or a refractory metal-containing alloy.
Claims15
A component of a magnetic recording medium, comprising a magnetic layer, a sealing layer on the magnetic layer, another sealing layer directly on the sealing layer, and a carbon overcoat on the another sealing layer, wherein the sealing layer comprises a refractory metal or a refractory metal-containing alloy and has a thickness of less than 10 Å and the another sealing layer comprises a refractory metal or a refractory metal-containing alloy.
A method for preventing corrosion of a magnetic layer due to contact start-stop of a recording medium, comprising exposing the magnetic layer to a refractory metal or a refractory metal-containing alloy, depositing a sealing layer comprising a second sealing layer directly on a first sealing layer and comprising the refractory metal or the refractory metal-containing alloy on the magnetic layer, and depositing a carbon overcoat on the second sealing layer, wherein the sealing layer prevents corrosion of the magnetic layer due to contact start-stop of the recording medium.
A method of manufacturing a component of a recording medium comprising depositing a first sealing layer on a magnetic layer, depositing a second sealing layer directly on the first sealing layer, and depositing a carbon overcoat on the second sealing layer, wherein the first sealing layer and the second sealing layer comprise a refractory metal or a refractory metal-containing alloy, wherein the first sealing layer has a thickness of less than 10 Å.
A component of a recording medium, comprising a first sealing layer on a magnetic layer, a second sealing layer directly on the first sealing layer and a carbon overcoat on the second sealing layer, wherein the first sealing layer and the second layer comprise a refractory metal or a refractory metal-containing alloy.
