Abstract:
1. A recording apparatus for recording data onto a recording medium having a first area for recording contents data and a second area, said apparatus comprising: a driver operable to rotate said recording medium; a memory operable to store identification information that is unique to said recording medium, wherein at least twelve bytes of parity information are added to said identification information; and a recording unit operable to record said identification information and said parity information onto said second area of said recording medium, wherein the information recorded into said second area of said recording medium is formatted into blocks of frames, each frame including synchronization data so that said blocks of frames include a plurality of frame syncs, and wherein the frame syncs of said plurality of frame syncs are arranged at equal intervals for one rotation of said recording medium such that when a frame sync of a frame is not detected, it is still possible to reproduce data succeeding the frame sync without loss of the data on the basis of interpolating timing of a frame sync previously detected, and wherein said identification information is modulated by a 4-1 modulation method.
