Abstract
A recording apparatus for use with a reproduction-only optical information storage medium, including: a recording unit which records data on the reproduction-only optical information storage medium; and a controller which controls the recording unit to form, on the reproduction-only optical storage medium, 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 reproduction-only 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.
Claims5
A reproducing and/or recording medium comprising a plurality of areas, the plurality of areas comprising:
- a burst cutting area;
- a lead-in area;
- a user data area;
- and
- a lead-out area;
- wherein the burst cutting area of the medium stores data of a bar-code configuration different from pits to identify the medium;
- wherein a first transition area is provided between the burst cutting area and the lead-in area;
- wherein the burst cutting area and the first transition area are outside the lead-in area;
- wherein at least one of the lead-in area, the user data area, and the lead-out area comprises:
- a first sub-area having a first track pitch;
- a second sub-area having a second track pitch different from the first track pitch;
- and
- a second transition area provided between the first sub-area and the second sub-area;
- and
- wherein a change in track pitch from the first track pitch to the second track pitch is realized in the second transition area.
A method of respectively recording and/or reproducing information on and/or from a recording and/or reproducing medium comprising a plurality of areas, the method comprising:
- recording and/or reproducing data in and/or from a recording and/or reproducing medium;
- wherein the plurality of areas comprise:
- a burst cutting area;
- a lead-in area;
- a user data area;
- and
- a lead-out area,
- wherein the burst cutting area of the medium stores data of a bar-code configuration different from pits to identify the medium, and a first transition area is provided between the burst cutting area and the lead-in area;
- wherein the burst cutting area and the first transition area are outside the lead-in area;
- wherein at least one of the of the lead-in area, the user data area, and the lead-out area comprises:
- a first sub-area having a first track pitch;
- a second sub-area having a second track pitch different from the first track pitch;
- and
- a second transition area provided between the first sub-area and the second sub-area;
- and
- wherein a change in track pitch from the first track pitch to the second track pitch is realized in the second transition area.
An apparatus to reproduce information stored in a reproducing and/or recording medium, the medium comprising a burst cutting area, a lead-in area, a user data area, a lead-out area, the apparatus comprising:
- an optical pickup configured to emit light to and receive reflected light from the medium;
- and
- a control unit configured to control the optical pickup to read information stored in the user data area;
- wherein the burst cutting area of the medium is configured to store data of a bar-code configuration different from pits to identify the medium;
- wherein a first transition area is provided between the burst cutting area and the lead-in area;
- wherein the burst cutting area and the first transition area are outside the lead-in area;
- wherein at least one of the of the lead-in area, the user data area, and the lead-out area comprises:
- a first sub-area having a first track pitch,
- a second sub-area having a second track pitch different from the first track pitch, and
- a second transition area provided between the first sub-area and the second sub-area;
- and
- wherein a change in track pitch from the first track pitch to the second track pitch is realized in the second transition area.
