wherein content from the read-only type disc of the optical recording medium is reproduced from the read-only type disc side of the recording medium, and
wherein content is recorded onto the pre-grooved disc of the optical recording medium through the pre-grooved disc side of the optical recording medium.
2. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium includes a plurality of pits configured to store a pre-recorded full-length title.
3. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium includes a plurality of pits configured to store an entire movie.
4. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium includes a plurality of pits configured to store an entire music album.
5. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium includes a plurality of pits configured to store an entire game.
6. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium includes in addition to pre-recorded content, a plurality of pits configured to store authorization information for additional content to be downloaded from a specified content source.
7. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium includes in addition to pre-recorded content, plurality of pits configured to store authorization information specifying content that that is authorized to be recorded onto the pre-grooved disc side of the optical recording medium.
8. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium stores pre-recorded content, and said pre-grooved disc of the optical recording medium is recordable.
9. An optical recording medium as claimed in claim 1 , wherein said read-only type disc of the optical recording medium stores pre-recorded content, and said pre-grooved disc of the optical recording medium is rewritable.
10. An optical recording medium as claimed in claim 1 , wherein said read-only type disc comprises a plurality of information layers.
11. An optical recording medium as claimed in claim 1 , wherein said pre-grooved disc of the optical recording medium includes a data capacity for recording full-length content.
12. An optical recording medium as claimed in claim 1 , wherein said pre-grooved disc of the optical recording medium includes a data capacity for storing an entire movie.
13. An optical recording medium as claimed in claim 1 , wherein said pre-grooved disc of the optical recording medium includes a data capacity for storing an entire music album.
14. An optical recording medium as claimed in claim 1 , wherein said pre-grooved disc of the optical recording medium includes a data capacity for storing an entire game.
15. An optical recording medium as claimed in claim 1 , wherein the optical recording medium including said pre-grooved disc bonded to said read-only type disc has a thickness in a range of 1.1mm to 1.5mm.
16. A method for manufacturing a hybrid optical recording medium, the method comprising:
providing a read-only type optical disc storing pre-recorded content; and
bonding a pre-grooved optical disc to the read-only type optical disc,
wherein said optical recording medium comprising the pre-grooved optical disc to the read-only type optical disc includes a read-only type disc side and a pre-grooved disc side that is different from the read-only type disc side,
wherein content in the read-only type disc of the optical recording medium is reproduced from the read only-type disc side of the optical recording medium, and
wherein content is recorded onto the pre-grooved disc of the optical recording medium through the pre-grooved disc side of the optical recording medium.
17. The method of claim 16 , wherein said read-only type disc of the optical recording medium includes a plurality of pits configured to store a pre-recorded full-length title.
18. The method of claim 16 , wherein said pre-grooved disc of the optical recording medium has a data capacity for recording full-length content.
19. The method of claim 16 , wherein said read-only type disc of the optical recording medium includes in addition to pre-recorded content, a plurality of pits configured to store authorization information for additional content to be downloaded from a specified content source.
20. The method of claim 16 , wherein said read-only type disc of the optical recording medium includes in addition to pre-recorded content, a plurality of pits configured to store authorization information specifying content that is authorized to be recorded onto the pre-grooved disc of the optical recording medium.
