Abstract
An optical information storage medium includes a plurality of areas and at least one transition area. Each transition area is located between two adjacent areas. The transition area allows data to be smoothly reproduced from the optical information storage medium at a low error generation rate. Also, since the optical information storage medium provides standards for the transition area, it is compatible with existing optical information storage media.
Claims2
An optical information storage medium comprising:
- a burst cutting area (BCA);
- a lead-in area;
- a user data area;
- a lead-out area;
- and
- a transition area,
- wherein at least one of the BCA, the lead-in area, the user data area, and the lead-out area is divided into a plurality of sub-areas, the plurality of sub-areas comprising a first sub-area having a first track pitch and a second sub-area having a second track pitch different from the first track pitch, and
- the transition area is located between the first sub-area and the second sub-area.
An apparatus to reproduce information stored in an optical information storage medium having a burst cutting area (BCA), a lead-in area, a user data area, a lead-out area, and a transition area, the apparatus comprising:
- an optical pickup to emit light to the optical information storage medium;
- and
- a control unit to control the optical pickup to read the information stored in the user data area,
- wherein at least one of the BCA, the lead-in area, the user data area, and the lead-out area is divided into a plurality of sub-areas, the plurality of sub-areas comprising a first sub-area having a first track pitch and a second sub-area having a second track pitch different from the first track pitch, and
- the transition area is located between the first sub-area and the second sub-area.
