Magnetic media made using planar magnetic heads. A head may comprise a substrate having conductive thru-hole vias extending therethrough, a first magnetic layer deposited and patterned on the substrate, a first insulation layer deposited and patterned on the first magnetic layer, a conductive coil layer deposited and patterned on the first insulation layer and connected to the conductive thru-hole vias, a second insulation layer deposited and patterned on the conductive coil layer, vias patterned into the insulation layer extending to the first magnetic layer, a second magnetic layer deposited in the vias, and a third magnetic layer deposited and patterned on the second insulation layer and second magnetic layer. The third magnetic layer may be connected to the first magnetic layer through the second magnetic layer deposited in the vias of the insulation layers.
Magnetic media comprising a plurality of servo tracks, each servo track having a unique servo track ID encoded in the magnetic transitions of the servo track.
