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.
