Abstract
A method of recording information to a read-only optical information storage medium comprising a plurality of areas, including: recording data in at least one of the plurality of areas in the form of pits in a first pit pattern; and recording data in others of the plurality of areas in the form of pits in a second pit pattern different from the first.
Claims19
A method of reproducing information from a read-only optical information storage medium having a burst cutting area comprising a bar code, a lead-in area, and a user data area, the method comprising:
- reproducing data from the burst cutting area, said burst cutting area having an area in which a pattern comprising a sequence of pits is repeatedly recorded;
- and
- reproducing data from the user data area,
- wherein the pattern comprising the sequence of pits is other than the bar code and the pattern comprising the sequence of pits indicates 00h,
- wherein a first recording modulation method used for the pattern comprising the sequence of pits is different from a second recording modulation method used in at least one of the lead-in area and the user data area, and
- wherein the second recording modulation method comprises a RLL (d, k) recording modulation method.
A method of recording information on a read-only optical information storage medium comprising a burst cutting area comprising a bar code, a lead-in area, and a user data area, comprising:
- recording a pattern comprising a sequence of pits in an area of the burst cutting area according to a first recording modulation method;
- and
- recording data in a form of pits in at least one of the lead-in area and the user data area according to a second recording modulation method,
- wherein the pattern comprising the sequence of pits is other than the bar code and the pattern comprising the sequence of pits indicates 00 h, and the first recording modulation method is different from the second recording modulation method, and
- wherein the second recording modulation method is a RLL (d, k) recording modulation method.
A reproducing apparatus for use with a read-only optical information storage medium comprising a burst cutting area having a bar code, a lead in area and a user data area, the apparatus comprising:
- a reading unit which reads data from the burst cutting area, the lead-in area and the user data area;
- and
- a controller configured to:
- control the reading unit to reproduce the data from the burst cutting area, said burst cutting area having an area in which a pattern comprising a sequence of pits is repeatedly recorded, and
- control the reading unit to reproduce the data from the user data area, wherein the pattern comprising the sequence of pits is other than the bar code and the pattern comprising the sequence of pits indicates OOh,
- wherein a first recording modulation method used for the pattern comprising the sequence of pits is different from a second recording modulation method used in at least one of the lead-in area and the user data area, and
- wherein the second recording modulation method comprises a RLL (d, k) recording modulation method.
A read-only optical information storage medium comprising:
- a burst cutting area having a bar code, a lead-in area, a data area, and a lead-out area, in which data is recorded in a form of pits, the burst cutting area having an area in which a pattern comprising a sequence of pits is repeatedly recorded, the pattern comprising the sequence of pits being other than the bar code and the pattern comprising the sequence of pits indicates OOh, a first recording modulation method used for the pattern comprising the sequence of pits being different from a second recording modulation method used in at least one of the lead-in area and the user data area, the second recording modulation method being a RLL (d, k) recording modulation method.
