US 7558175 B2Abstract
FIGS. 10 a to 10 c show ways to write a physical address in a linking area in accordance with an exemplary embodiment of the present invention; FIG. 11 a is a block diagram of an exemplary linking frame constructing circuit to create a linking frame with input user data as shown in FIG. 4 a; FIG. 11 b is a block diagram of an exemplary linking frame constructing circuit to create a linking frame with input user data as shown in FIG. 4 d; FIG. 12 a shows an exemplary physical address allocated in the linking frame shown in FIG. 4 b; FIG. 12 b is an exemplary block diagram of a scrambler to scramble user data into the linking frame shown in FIG. 12 a; FIG. 13 is an exemplary block diagram of a scrambler to scramble user data into the linking frame shown in FIG. 4 c; FIGS. 14 a to 14 c illustrate exemplary user data spaces of linking frames where user data of arbitrary values are written;
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’(FS1) 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. The first case illustrated in FIG. 6 b is the exemplary embodiment of FIGS. 3A and 3B. In this exemplary embodiment, two 1932-channel-bit recording frames are recorded in a linking area and each recording frame is composed of a frame sync, a physical address, user data, and parity. At least one of the two recording frames may include the newly-defined frame sync ‘FS n’.
However, as depicted in the ‘B’-marked case of FIG. 7 b, the first linking frame (frame #31) and the second linking frame (frame #32), which are in accordance with exemplary embodiments of the present invention, have the same frame sync sequence at frames N and N-3, which could cause a problem in defining a linking area. However, because the two linking frames have the newly-defined frame sync FS7, this case of FS7-FS7 would make it easier to detect a linking area, than the case of FS0-FS7 of FIG. 7 a. FIG. 7 c shows the case where FS7 and FS8 are used. As the case (1) shows, the frame sync sequence ahead of the frame #0 is FS8/FS2, FS7/FS4 and FS2/FS4 and the frame #0 is the first or the middle address unit of RUB. As the case (2) shows, the frame sync sequence before the frame #1 is FS0, FS8/FS2 and FS7/FS4 and the frame #1 is the first or the middle unit of RUB.
