Background Art
Optical information storage media, for example, optical disks, are widely used in optical pickup apparatuses for recording/reproducing information in a non-contact way. Optical disks are classified as compact disks (CDs) or digital versatile disks (DVDs) according to their information storage capacity. Examples of recordable optical disks are 650MB CD-R, CD-RW, 4.7GB DVD+RW, and the like. Furthermore, HD-DVDs having a recording capacity of 20GB or greater are under development.
The compatibility of the above optical information storage media with one another increases user convenience. In consideration of the economical efficiency and the convenience of users, storage media have different standards for different types. Storage media that have no determined standards yet are undergoing standardization. To achieve this standardization, a storage medium must be developed that has a format that can guarantee compatibility and consistency with existing storage media.
A conventional reproduction-only optical disk includes a burst cutting area (BCA), a lead-in area, a user data area, and a lead-out area. The BCA stores information about the serial number of the optical disk, and the lead-in area stores disk-related information. Here, the serial number of the optical disk is recorded as a barcode. The BCA, the lead-in area, the user data area, and the lead-out area are consecutively arranged with no transition areas between adjacent areas. However, when the BCA, the lead-in area, and the user data area have different pit patterns, consecutive data reproduction may not be properly performed because of the absence of transition areas.

Best mode for carrying out the Invention
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures. An optical information storage medium according to various embodiments of the present invention is reproduction-only, and the entire area thereof is formed of pits. The optical information storage medium according to various embodiments of the present invention is divided into a plurality of areas according to function. As shown in FIG. 1 , the optical information storage medium according to an embodiment of the present invention includes a burst cutting area (BCA) 10, a lead-in area 20, a user data area 30 for storing user data, and a lead-out area 40, which are sequentially formed from the inner boundary to the outer boundary of the optical information storage medium. The BCA 10 stores the serial number of an optical information storage medium, for example, an optical disk, or data identifying the BCA. The lead-in area 20 stores disk-related information, copy protection information, and the like. Examples of the disk-related information are information about the type of information storage medium, such as a recordable disk, a write-one disk, or a reproduction-only disk, information about the number of recording layers, information about a recording speed, information about the disk size, and the like.
Referring to FIG. 2A through 2F, an optical information storage medium according to a first embodiment of the present invention includes a first transition zone 15 between the BCA 10 and the lead-in area 20. The BCA 10 stores data recorded in a first straight pit pattern. The lead-in area
20 stores data that may be recorded in a second straight pit pattern, which is different from the first straight pit pattern, or in a wobbling pit pattern. Alternatively, the BCA 10 stores data recorded in a first wobbling pit pattern, and the lead-in area 20 stores data that may be recorded in a second wobbling pit pattern, which is different from the first wobbling pit pattern, or in a straight pit pattern. A straight pit pattern denotes an arrangement of pits along a straight line, and a wobbling pit pattern denotes an arrangement of pits along a wavy line.
The first and second straight pit patterns and the first and second wobbling pit patterns may be classified as a single pattern, a specific pattern, or a random pattern. The single pattern denotes a pattern in which pits, each having an identical length (nT), are arranged at regular intervals. Here, n denotes a natural number, and T denotes the minimum length of a pit. For example, a straight single pit pattern denotes a pattern in which pits each having an identical length are arranged along a straight line. A wobbling single pit pattern denotes a pattern in which pits each having an identical length are arranged along a wavy line. The specific pattern denotes a repetition of a pattern of pits having different lengths. For example, a pattern of a 3T pit and a 6T pit repeats. A straight specific pit pattern denotes a repetition of a pattern of pits that have different lengths along a straight line. A wobbling specific pit pattern denotes a repetition of a pattern of pits with different lengths along a wavy line. The random pattern denotes a random arrangement of pits having different lengths. For example, a straight random pit pattern denotes a random arrangement of pits with different lengths along a straight line. A wobbling random pit pattern denotes a random arrangement of pits with different lengths along a wavy line.
Because the BCA 10 and the lead-in area 20 have different pit patterns, the first transition area 15 is included between the BCA 10 and the lead-in area 20 in order to prevent an improper consecutive reproduction of data. The first transition area 15 stores data identifying a transition area.
FIG. 2A through 2E show examples of a pit pattern for the first transition area 15 when the BCA 10 is formed of pits in a straight single pattern and the lead-in area 20 is formed of pits in a straight random pattern. As shown in FIG. 2A, data is recorded in the BCA 10 in the form of a straight single pattern of pits, data is recorded in the lead-in area 20 in the form of a straight random pattern of pits, and the first transition area 15 between the BCA 10 and the lead-in area 20 is formed of a straight single pattern of pits. Although not shown, the first transition area 15 may be formed of a wobbling single pattern of pits. As shown in FIG. 2B, data is recorded in the BCA 10 in the form of a straight single pattern of pits, data is recorded in the lead-in area 20 in the form of a straight random pattern of pits, and the first transition area 15 between the BCA 10 and the lead-in area 20 is formed of a straight random pattern of pits. Although not shown, the first transition area 15 may be formed of a wobbling random pattern of pits. As shown in FIG. 2C, data is recorded in the BCA 10 in the form of a straight single pattern of pits, data is recorded in the lead-in area 20 in the form of a straight random pattern of pits, and the first transition area 15 between the BCA 10 and the lead-in area 20 is a mirror area.
As shown in FIG. 2D, data is recorded in the BCA 10 in the form of a straight single pattern of pits, data is recorded in the lead-in area 20 in the form of a straight random pattern of pits, and the first transition area 15 between the BCA 10 and the lead-in area 20 is formed of a straight specific pattern of pits.
Alternatively, the first transition area 15 may be formed of a wobbling single pattern of pits, a wobbling random pattern of pits, or a wobbling specific pattern of pits. In FIG. 2E, the first transition area 15 is formed of a wobbling random pattern of pits. Although FIGS. 2A through 2E show the BCA 10 formed of a straight single pattern of pits, the BCA 10 may be formed of a wobbling single pattern of pits.

As described above, when pits are formed in the BCA 10 in a straight random pattern or in a wobbling random pattern, information containing a content, for example, OOh or BCA, is recordable in the BCA 10.
Although only the case where pits are formed in the BCA 10 in a straight pattern has been described above, the BCA 10 may be formed of a wobbling pattern of pits. For example, pits may be formed in the BCA 10 in a wobbling single pattern, in a wobbling specific pattern, or in a wobbling random pattern.
Pits may be formed in the BCA 10 in a straight pattern or a wobbling pattern and pits are formed in the lead-in area 20 in a wobbling pattern.

Referring to FIG. 5E, pits are formed in the first transition area 15 in a wobbling random pattern. Although FIGS. 5A through 5E show the BCA 10 where pits are formed in a straight single pattern, pits may be formed in the BCA 10 in a wobbling single pattern. FIGS. 6A through 6E show examples of a pit pattern formed in the first transition area 15 when pits are formed in the BCA 10 in a straight specific pattern and pits are formed in the lead-in area 20 in a wobbling random pattern.

Referring to FIG. 6C, the first transition area 15 is a mirror area. Referring to FIG. 6D, pits are formed in the first transition area 15 in a straight specific pattern. Alternatively, pits may be formed in the first transition area 15 in a wobbling single pattern, a wobbling random pattern, or a wobbling specific pattern. For example, FIG. 6E shows the first transition area 15 where pits are formed in a wobbling random pattern. Although FIGS. 6A through 6E show the BCA 10 where pits are formed in a straight specific pattern, pits may be formed in the BCA 10 in a wobbling specific pattern.
FIGS. 7A through 7F show examples of a pit pattern formed in the first transition area 15 when pits are formed in the BCA 10 in a straight random pattern and pits are formed in the lead-in area 20 are formed in a wobbling random pattern. Referring to FIG. 7A, pits are formed in the first transition area 15 in a straight single pattern. Referring to FIG. 7B, pits are formed in the first transition area 15 in a straight random pattern. Referring to FIG. 7C, the first transition area 15 is a mirror area. Referring to FIG. 7D, pits are formed in the first transition area 15 in a straight specific pattern. Alternatively, pits may be formed in the first transition area 15 in a wobbling single pattern, a wobbling random pattern, or a wobbling specific pattern. For example, FIG. 7E shows the first transition area 15 where pits are formed in a wobbling random pattern. Although FIGS. 7A through 7E show the BCA 10 where pits are formed in a straight random pattern, pits may be formed in the BCA 10 in a wobbling random pattern. When pits are formed in the BCA 10 in a straight random pattern or a wobbling random pattern as described above, information containing a content, such as, OOh or BCA, is recordable in the BCA 10.
When pits are formed in the BCA 10, the first transition area 15, or the lead-in area 20 in a wobbling pattern, they are formed so that the amplitude of a wobble gradually increases or decreases. As shown in FIG. 7F, the pits are formed in the first transition area 15 in a wobbling pattern so that the amplitude of a wobble can gradually increase.
The BCA 10, the first transition area 15, and the lead-in area 20 may have either an identical track pitch or different track pitches. For example, the BCA 10 and the first transition area 15 have the same track pitch, and only the lead-in area 20 has a different track pitch. Alternatively, the first transition area 15 and the lead-in area 20 may have the same track pitch, and only the BCA 10 has a different track pitch. When the BCA 10 and the lead-in area 20 have different track pitches, the first transition area 15 is formable so that its track pitch can gradually increase or decrease. For example, when a track pitch for the BCA 10 is "a" and a track pitch for the lead-in area 20 is "b" (b>a), the first transition area 15 is formed so that its track pitch can gradually increase from "a" to "b". An optical information storage medium according to a second embodiment of the present invention includes the BCA 10, the lead-in area 20, the user data area 30, and the lead-out area 40. A second transition area 25 is further included between the lead-in area 20 and the user data area 30.
