Abstract:
A method for manufacturing a bit patterned magnetic media for magnetic data recording. The method includes patterning a topography that includes an array of raised regions separated by a recessed portion. The array can be patterned by micro-printing using a stamp that has raised islands. The raised regions can have a height of 1 to 5 nm as measured from the recessed region. A magnetic alloy and a non-magnetic segregant are then co-sputtered. The magnetic alloy preferentially grows over the raised portions and the non-magnetic segregant grow preferentially over the recessed region between the raised portions.
