Optical recording medium, apparatus and method of manufacturing optical recording medium, and apparatus and method of recording/reproducing data of optical recording medium

An apparatus for recording/reproducing data of an optical recording medium comprising a first area and a second area, the apparatus comprising:

• a signal processor configured to process a signal of a wobble address from the optical recording medium, wherein the first area comprises a plurality of recording unit blocks, and the second area comprises a plurality of recording unit blocks, and
• wherein
• each of the plurality of recording unit blocks in the first area and the second area, comprises the wobble address corresponds to each recording unit block on which the data is recorded/reproduced on/from the optical recording medium,
• the wobble address comprises a plurality of address units (ADIPs),
• last two bits in the ADIPs of the wobble address of each recording unit block arranged in the first area are one of:
• 00, 10 and 01, and
• last two bits in at least one ADIP of the wobble address of each recording unit block arranged in the second area are 11;
• and
• a controller configured to control the signal processor to record the data on the recording unit block corresponding to the wobble address detected by processing the signal or to read the data from the recording unit block corresponding to the wobble address.

A method of recording/reproducing data of an optical recording medium comprising a first area and a second area, the method comprising:

• processing a signal of a wobble address from the optical recording medium,
• wherein the first area comprises a plurality of recording unit blocks and the second area comprises a plurality of recording unit blocks,
• wherein each of the plurality of recording unit blocks in the first area and the second area comprises the wobble address corresponding to each recording unit block on which the data is recorded/reproduced on/from the optical recording medium, and
• wherein the wobble address to comprise a plurality of address units (ADIPs), wherein last two bits in the ADIPs of the wobble address of each recording unit block arranged in the first area are one of:
• 00, 10 and 01, and last two bits in at least one ADIP of the wobble address of each recording unit block arranged in the second area are 11;
• and
• recording the data on the recording unit block corresponding to the wobble address detected by the processing of the signal or reading the data from the recording unit block corresponding to the wobble address.

An apparatus for reproducing data from an optical recording medium comprising a first area and a second area, the apparatus comprising:

• a pickup configured to emit or receive a light to transfer data from the optical recording medium;
• and
• a controller configured to control the pickup to read data from the first area or the second area of the optical recording medium, wherein the first area comprises a plurality of recording unit blocks and the second area comprises a plurality of recording unit blocks, and
• wherein
• each of the plurality of recording unit blocks in the first area and the second area comprises a wobble address corresponding to each recording unit block comprising a plurality of address units (ADIPs),
• last two bits in the ADIPs of the wobble address of each recording unit block arranged in the first area are one of:
• 00, 10 and 01, and
• last two bits in at least one ADIP of the wobble address of each recording unit block arranged in the second area are 11.
