Patent ID: 8298611

Claim:
A method of fabricating a magnetic recording structure having a plurality of tracks, each track having a width, comprising: depositing, on a cylindrical base, a first layer having a first thickness, the first layer comprising one of a magnetic layer from a first target and a non-magnetic layer from a second target; depositing, on the first layer, a second layer having a second thickness, the second layer comprising the other of the magnetic layer from the first target and the non-magnetic layer from the second target; repeating depositing of the first and second layers a predetermined number of times to produce a plurality of magnetic layers and a plurality of non-magnetic layers interposed between the plurality of magnetic layers on the cylindrical base to provide a layered source from which the magnetic recording structure can be formed; heating an end surface of the layered source to a predetermined temperature; and transferring the heated end surface of the layered source to a base disk by stamping the heated end surface onto the base disk to produce the magnetic recording structure; wherein the magnetic recording structure includes the base disk having a plurality of concentric magnetic layers and a plurality of concentric non-magnetic layers interposed between the plurality of the concentric magnetic layers stamped thereon, wherein the thickness of each of the plurality of magnetic layers on the cylindrical base corresponds to the track width of the magnetic recording structure.
