Abstract
A recording medium, such as a high-density and/or read-only recording medium including a data area including at least two data sections and a linking area to link neighboring data sections, the linking area including scrambled user data produced by scrambling user data with a scrambling key, and to methods and apparatuses for forming, recording, and reproducing the recording medium.
Claims37
A recording medium, comprising:
- a data area including at least two data sections;
- and
- a linking area to link neighboring data sections, the linking area including scrambled user data produced by scrambling user data with a scrambling key.
A method of forming a recording medium, comprising:
- scrambling user data with a scrambling key;
- and
- writing the scrambled user data in a linking area to link neighboring data sections of a data area on the recording medium.
A method of reproducing data from a recording medium, comprising:
- utilizing a linking area, including scrambled user data, which links neighboring data sections of a data area, to reproduce the data.
A method of recording data on a recording medium, comprising:
- utilizing a linking area, including scrambled user data, which links neighboring data sections of a data area, to record the data.
An apparatus for reproducing data from a recording medium, said apparatus utilizing a linking area, including scrambled user data, which links neighboring data sections of a data area, to reproduce the data.
A method of scrambling data for recording on a recording medium, comprising:
- loading a partial physical address into a shift register;
- outputting a scrambling byte for each shift of the shift register;
- and
- combining each scrambling byte with a byte of user data.
A method of constructing a linking frame on a recording medium, comprising:
- scrambling user data with a scrambling key
- combining additional data with the scrambled user data;
- and
- writing the combined scrambled data as the linking frame to link neighboring data sections of a data area on the recording medium.
