The Run-in area, as shown in FIG. 2 a, may include a 1100-channel-bit guard ‘Guard_1’ and a 1660-channel-bit preamble ‘PrA’. 55 repetitions of a 20-channel-bit pattern are written in the guard ‘Guard_1’ to indicate the head of an RUB while the first sync data ‘Sync_1’ and the second sync data ‘Sync_2’, which are 30 channel bits in length, are written in the preamble ‘PrA’. Each sync data is composed of 24-bit sync body and 6-bit sync ID. The sync IDs of the first and the second sync data are ‘000 100’ (FS4) and ‘010 000’ (FS6), respectively.
The Run-out, as shown in FIG. 2 b, is composed of a 540-channel-bit guard ‘Guard_2’ and a 564-channel-bit post-amble ‘PoA’ including the third sync data ‘Sync_3’. The third sync data also includes a 24-bit sync body and 6-bit sync ID. The third sync ID is ‘000 001’ (FS0).
While sync IDs of sync data in a preamble of a BD-RE may be ‘000 100’ and ‘010 000’ as shown in FIG. 2 a, the preamble of a BD-ROM structured in accordance with exemplary embodiments of the present invention may include two sync data whose IDs are FS0 (‘000 001’) (Sync_3) and FS6 (‘010 000’) (Sync_2). The sync data ‘Sync_3’ may be placed ahead of the sync data ‘Sync_2’.
In addition, the post-amble ‘PoA’ in the Run-out area of a BD-ROM structured in accordance with exemplary embodiments of the present invention, as shown in FIG. 3 b, may include sync data whose ID is FS4 (‘000 100’) (Sync_1). This is different from a BD-RE in that sync data with sync ID of FS0 (‘000 001’) is written in the post-amble of a BD-RE.
In an exemplary embodiment of the present invention, at least one linking frame of the two shown in FIGS. 4 a-4 d may use a new frame sync ‘FS n’ that is different in sync ID from the seven frame syncs used for BD-RE. Examples of the sync ID of the new frame sync ‘FS n’ are ‘100 101’ (FS7), ‘101 010’ (FS8), ‘010 101’ (FS9), or ‘101 001’ (FS10), as shown in FIG. 5.
The Prohibit RMTR constraint, which ensures stable detection of an RF signal, states that a minimum run length 2T, namely, ‘01’ or ‘10’ must not be repeated continuously more than six times. Therefore, a frame sync with a smaller transition frequency may be used, namely, ‘100 101’ (FS7) or ‘101 001’ (FS10) among the new frame syncs to make successive bit trains satisfy the Prohibit RMTR constraint. The usage of frame syncs is explained in more detail with reference to FIGS. 6 a-6 b.
A second case illustrated in FIG. 6 b is the exemplary embodiment of FIG. 4A. In this exemplary embodiment, two 1932-channel-bit recording frames may be recorded in a linking area and each recording frame may be composed of a frame sync, a physical address, user data, and parity. At least one of the two recording frames includes the frame sync FS0 (‘000 001’) and another one of the newly-defined frame syncs ‘FS n’.
For instance, both the first and the second frame syncs use one of the new frame syncs, such as, FS7 (‘010 101’), FS8 (‘101 010’), or FS9 (‘100 101’).
In case that the new frame sync FS7 (‘100 101’) is used, the RMTR constraint can be satisfied by writing user data space following the frame sync having data other than “01 11 01 11”.
A fourth case illustrated in FIG. 6 b is the exemplary embodiment of FIG. 4C. In this exemplary embodiment, two 1932-channel-bit recording frames may be recorded in a linking area and each recording frame may be composed of a frame sync, a physical address, user data, and parity. Both recording frames may include the new frame sync FS10 (‘101 001’, as an example.
