Abstract
An information storage medium having a lead-in area, a user data area, and a lead-out area, wherein information regarding whether additional information is recorded as wobbling pits is recorded in at least a portion of at least one of the lead-in and the lead-out areas.
Claims22
An information storage medium comprising:
- a lead-in area having data recorded as wobbling pits and data recorded as non-wobbling pits;
- a user data area;
- and
- a lead-out area having data recorded as wobbling pits and data recorded as non-wobbling pits;
- wherein information regarding whether additional information is recorded as wobbling pits is recorded as non-wobbling pits on at least a portion of at least one of the lead-in and the lead-out areas.
An information storage medium comprising:
- a lead-in area having data recorded as wobbling pits and data recorded as non-wobbling pits;
- a user data area;
- and
- a lead-out area having data recorded as wobbling pits and data recorded as non-wobbling pits;
- wherein information regarding whether additional information is recorded other than in pits is recorded as non-wobbling pits on at least a portion of at least one of the lead-in and the lead-out areas.
A method of recording/reproducing data on/from an information storage medium having a lead-in area, a user data area, and a lead-out area, the method comprising:
- recording information as non-wobbling pits on at least a portion of at least one of the lead-in and the lead-out areas, the information regarding whether additional information is recorded as wobbling pits;
- reading the information regarding the additional information in response to the information storage medium being loaded;
- and
- reading the additional information according to the read information.
A method of recording/reproducing data on/from an information storage medium having a lead-in area, a user data area, and a lead-out area, the method comprising:
- recording information as non-wobbling pits on at least a portion of at least one of the lead-in and the lead-out areas, the information regarding whether additional information is recorded other than as pits;
- and
- reproducing the additional information according to the recorded information regarding the additional information.
An apparatus to record/reproduce data on/from an information storage medium, the apparatus comprising:
- a reading unit to read information recorded as non-wobbling pits, the information regarding whether additional information is recorded as wobbling pits on the information storage medium;
- and
- a controller to control the reading unit to reproduce the additional information according to the information read by the reading unit.
An information storage medium wherein information regarding whether a pit sequence is wobbled is recorded as non-wobbling pits separately from the wobbled pit sequence on the information storage medium.
A method of recording/reproducing data on/from an information storage medium, comprising:
- recording/reproducing disk-related data as/from non-wobbling pits, wherein the disk-related data is information regarding whether additional information is recorded as wobbling pits on the information storage medium;
- and
- modulating and demodulating the disk-related data in a different way than user data recorded on the information storage medium.
