Replica disk for data storage
View Patent ↗Data storage replica disks having a surface relief pattern with replica lands and replica grooves are provided.
1. A disk for storing information, comprising:
a surface including tracks comprising lands and pits, wherein the surface corresponds to a recording layer of the disk, wherein the tracks have a track pitch that is less than 375 nm, wherein the pits have a pit depth, and wherein the pit depth ranges from 55 nm to 110 nm.
2. The disk of claim 1 , wherein the pit depth ranges from 78 nm to 110 nm.
3. The disk of claim 1 , wherein the pit depth ranges from 91 nm to 110 nm.
4. The disk of claim 1 , wherein the disk is a replica disk that is formed from a master stamper disk.
5. The disk of claim 1 , wherein the tracks are spiral tracks defined by adjacent lands and pits.
6. The disk of claim 1 , wherein the lands are substantially flat.
7. The disk of claim 1 , wherein the disk for storing information is a DVD disk.
8. The disk of claim 1 , wherein the lands and pits represent information encoded on the surface.
9. The disk of claim 1 , wherein the tracks are concentric spiral tracks, spaced radially from a disk center, defined by adjacent lands and pits.
10. A disk for storing information, comprising:
a surface including tracks comprising lands and pits, wherein the surface corresponds to a recording layer of the disk, wherein the tracks have a track pitch that is less than 375 nm, wherein the pits have a pit depth, and wherein the pit depth ranges from 64 nm to 91 nm.
11. The disk of claim 10 , wherein the pit depth ranges from 78 nm to 91 nm.
12. The disk of claim 10 , wherein the disk is a replica disk that is formed from a master stamper disk.
13. The disk of claim 10 , wherein the tracks are spiral tracks defined by adjacent lands and pits.
14. The disk of claim 10 , wherein the lands are substantially flat.
15. The disk of claim 10 , wherein the disk for storing information is a DVD disk.
16. The disk of claim 10 , wherein the lands and pits represent information encoded on the surface.
17. The disk of claim 10 , wherein the tracks are concentric spiral tracks, spaced radially from a disk center, defined by adjacent lands and pits.
18. A disk for storing information, comprising:
a surface including tracks comprising lands and pits, wherein the surface corresponds to a recording layer of the disk, wherein the tracks have a track pitch that is less than 375 nm, wherein the pits have a pit depth, wherein the pit depth ranges from 55 nm to 110 nm, wherein the lands have a land width, and wherein the land width ranges from between 25 percent of the track pitch and 140 nm.
19. The disk of claim 18 , wherein the pit depth ranges from 78 nm to 91 nm.
20. The disk of claim 18 , wherein the tracks are concentric spiral tracks, spaced radially from a disk center, defined by adjacent lands and pits.
