According to the apparatus and method, parameters of recording characteristics appropriate to a recording and/or reproducing apparatus and compatibility between different specifications can be achieved.
1. An apparatus for obtaining recording related parameters appropriate to recording characteristics of an optical recording medium, the apparatus comprising:
a pickup which emits or receives a light to transfer data with respect to the optical recording medium comprising a lead-in area, an user data area, and a lead-out area, the lead-in area comprising a pre-recorded area and a recordable area; and
controls the pickup to read at least one disk information structure from the pre-recorded area of the optical recording medium, each disk information structure comprising a pair of tables, a first table comprising recording characteristics information comprising a recording speed and a write strategy (WS) indication information, the WS indication information being information on a type of write strategy, and a second table comprising recording related parameters being used in setting the apparatus to a condition corresponding to the recording speed and the WS indication information,
determines recording characteristics comprising a recording speed and a write strategy, to be applied to the optical recording medium,
selects one disk information structure corresponding to the determined recording characteristics from the at least one disk information structure using the recording characteristic information included in the first table, and
controls the pickup to read the recording related parameters of the second table included in the selected disk information structure.
2. The apparatus of claim 1, wherein the disk information structure is arranged according to a sequence in which the recording speed increases.
3. An information storage medium comprising a lead-in area, an user data area, and a lead-out area, the lead-in area comprising a pre-recorded area and a recordable area, wherein:
the pre-recorded area comprises one or more disk information structures, each disk information structure comprising a pair of tables, a first table comprising recording characteristics information comprising a recording speed and a write strategy (WS) indication information, the WS indication information being information on a type of write strategy, and a second table comprising recording related parameters being used in setting a recording and/or reproducing apparatus to a condition corresponding to the recording speed and the WS indication information.
4. The information storage medium of claim 3, wherein the recording related parameters further comprises an initial pulse cycle (Ttop), a middle pulse cycle (Tmp), an end pulse cycle (Tcl), a recording power (Pw), a delete power (Pe), and a bias power (Pb).
5. A method of recording and/or reproducing data on and/or from an optical recording medium comprising a lead-in area, an user data area, and a lead-out area, the lead-in area comprising a pre-recorded area and a recordable area, the method comprising:
reading at least one disk information structure from the pre-recorded area of the optical recording medium, each disk information structure comprising a pair of tables, a first table comprising recording characteristics information comprising a recording speed and a write strategy (WS) indication information, the WS indication information being information on a type of write strategy, and a second table comprising recording related parameters being used in setting a recording and/or reproducing apparatus to a condition corresponding to the recording speed and the WS indication information;
selecting one disk information structure corresponding to the determined recording characteristics from the at least one disk information structure using the recording characteristic information included in the first table; and
reading the recording related parameters of the second table included in the selected disk information structure.
Generally, an optical disk is widely used as an information storage medium in an optical pickup apparatus for recording and/or reproducing information. According to the information recording capacity, the optical disc is classified into a compact disk (CD) and a digital versatile disk (DVD). Optical disks capable of recording, deleting, and reproducing data include a 650 MB CD-R, a CD-RW, and a 4.7 GB DVD+RW, and optical disks for reproducing data include a 650 MB CD, and a 4.7 GB DVD-ROM. Furthermore, a HD-DVD having a recording capacity of over 25 GB is under development.
