Various protective carbon layers deposited on the surface of CoNi magnetic layer on the Cr/NiP pretreated aluminium alloy substrate are studied in view of wear resistance. Microstructure of the carbon layer is controlled by varying sputtering conditions and targets, especially glass-like carbon target. It is formed that the most wear resistive layer has an amorphous structure characterized by a single 1550cm-1 peak in the Raman spectrum, while the other layers have ordinary graphite spectrum, with two peaks at 1360cm-1 and 1580cm-1.
