Abstract
A method of manufacturing a magnetic recording medium includes co-depositing a magnetic material and non-magnetic material over a substrate using a thin-film deposition technique to define a recording layer and removing at least a portion of the non-magnetic material from the recording layer to form reservoirs within the recording layer.

A method of manufacturing a magnetic recording medium, the method comprising:
- co-depositing a magnetic material and non-magnetic material over a substrate using a thin-film deposition technique to define a recording layer;
- and
- removing at least a portion of the non-magnetic material from the recording layer to form reservoirs within the recording layer.
A magnetic recording medium comprising:
- a substrate;
- and
- a thin-film recording layer extending over the substrate and including a magnetic material, the recording layer defining a recording surface opposite the substrate and a plurality of reservoirs extending from the recording surface toward the substrate, each of the plurality of reservoirs having been formed by removing a non-magnetic material from the thin-film recording layer, wherein the non-magnetic material was initially co-deposited over the substrate with the magnetic material.
