Heated Dot Magnetic Recording Media - Path to 10 Tdots/in2

Density of up to 2 Tdpsi (Figure 2) have been fabricated. Subsequent media fabrication involves transferring the nano features from a template into magnetic thin films by NIL and ion-beam etching (IBE). Using this approach, HDMR media with fully functional integrated servo features has been successfully fabricated on 2.5” disks with areal density of up to 2.0 Tdpsi. On a spinstand, track-following capability and basic read-write functionality of a 1.5 Tdpsi HDMR media has been demonstrated.
