Medium, method of fabricating a medium, recording system and method of controlling a recording system
View Patent ↗A medium may be provided. The medium includes a servo layer, a data recording layer, and a heat sink layer disposed between the servo layer and the recording layer.
1. A medium, comprising:
a servo layer;
a data recording layer;
a heat sink layer disposed between the servo layer and the data recording layer;
wherein the servo layer and the data recording layer are separate magnetic layers.
2. The medium according to claim 1 , further comprising:
a thermal isolating layer, an intermediate layer and a thermal conditioning layer;
wherein the thermal isolating layer is disposed above the servo layer, and the intermediate layer, the heat sink layer and the thermal conditioning layer are disposed between the data recording layer and the thermal isolating layer.
3. The medium according to claim 2 ,
wherein the intermediate layer is disposed above the thermal isolating layer, the heat sink layer is disposed above the intermediate layer, and the thermal conditioning layer is disposed above the heat sink layer.
4. The medium according to claim 2 ,
wherein the heat sink layer is disposed above the thermal isolating layer, the intermediate layer is disposed above the heat sink layer, and the thermal conditioning layer is disposed above the intermediate layer.
5. The medium according to claim 2 ,
wherein the heat sink layer is disposed above the thermal isolating layer, the thermal conditioning layer is disposed above the heat sink layer, and the intermediate layer is disposed above the thermal conditioning layer.
6. The medium according to claim 1 ,
further comprising a diamond-like carbon layer with lubricant covering disposed above the data recording layer.
7. The medium according to claim 1 ,
further comprising a further intermediate layer;
wherein the servo layer is disposed above the further intermediate layer.
8. The medium according to claim 7 ,
further comprising a substrate;
wherein the further intermediate layer is disposed above the substrate.
9. The medium according to claim 8 ,
further comprising a magnetic soft under-layer disposed between the substrate and the further intermediate layer.
10. A method of fabricating a medium, the method comprising:
disposing a servo layer above a substrate;
disposing a heat sink layer above the servo layer;
disposing a data recording layer above the heat sink layer;
wherein the servo layer and the data recording layer are separate magnetic layers.
