A sliding member includes: a lining layer formed from an alloy having a predetermined shape; and an overlay layer formed on an inner circumferential surface of the lining layer, the overlay layer being formed of a resin, the overlay layer sliding with a shaft, the overlay layer including a raised portion a height of which in a predetermined area including each of an edge in an axial direction of the shaft is greater than a height of another area of the overlay layer.

Bearing 13 has lining layer 17 that is formed of an alloy having a predetermined shape and that has chamfered portion 25, and overlay layer 19 that is formed of a resin on an inner circumferential surface of lining layer 17, the inner circumferential surface sliding relative to a mating shaft, and that covers at least a portion of chamfered portion 25.

Provided is a coated steel sheet having excellent press formability. The coated steel sheet includes a base steel sheet and, on at least one side of the base steel sheet, a film containing organic resin and wax. The organic resin is at least one selected from the group consisting of acrylic resins, epoxy resins, urethane resins, phenolic resins, vinyl acetate resins, and polyester resins. The wax is polyolefin wax having a melting point that is 100 C. or more and 145 C. or less and an average particle size that is 3.0 m or less. The proportion of the wax in the film is 5 mass % or more and 70 mass % or less. Coating weight variation is 0.300 or less. Coating weight .sub.W of the film is 0.3 g/m.sup.2 or more.

A lubricant for magnetic media is synthesized using click chemistry. In one aspect the lubricant is according to general formula (I):

##STR00001##

where Rc is a fluorinated or non-fluorinated divalent linking segment; where each Re.sup.1 and Re.sup.2 is a click linker moiety that can be triazole or sulfone; n is from 2 to 50; where each Rb.sup.1 and Rb.sup.2 is an optionally non-fluorinated divalent linking segment optionally comprising at least one least one first anchoring functional group engageable with a protective overcoat of a magnetic recording medium; and where each of Rv.sup.1 and Rv.sup.2, when present, independently comprises a moiety having at least one second anchoring functional group engageable with the protective overcoat of the magnetic recording medium. The click linker moiety may also functional as an anchoring functional group.
