Abstract: Data is written to data sectors of a heat-assisted magnetic recording (HAMR) medium using a laser of a HAMR head supplied with a sum of an operational current and a threshold current. A service current is supplied to the laser when the head is over servo sectors of the medium, such that a temperature of the medium at the servo sectors is greater than or equal to a temperature of the head when over the servo sectors.

Abstract: Systems and methods for treating a carbon overcoat surface are described. In one embodiment, the method may include depositing a magnetic recording layer over a substrate, depositing a carbon overcoat layer over the magnetic recording layer, and exposing a carbon overcoat layer to water in gas phase after the carbon overcoat layer is deposited on the magnetic recording layer. In some cases, the method may include depositing a lubricant over the outer surface of the carbon overcoat after exposing the carbon overcoat layer to the water in gas phase.

Abstract: Systems and methods for adding a cap-layer to magnetic recording media are described. In one embodiment, the method may include depositing a magnetic recording layer over a substrate, depositing an interface layer over the magnetic recording layer, and depositing a carbon overcoat layer over the interface layer. In some cases, sputter deposition is used to deposit at least the interface layer. In some cases, oxygen is used as a background gas of the sputter deposition.
