DIGITAL DATA SIGNAL RECORDING DEVICE AND METHOD THEREOF; RECORD MEDIUM Russian patent published in 2003 - IPC

FIELD: recording digital data signal and subcode signal in tilted tracks on record medium. SUBSTANCE: device has input means for digital data signal and subcode signal; formatting means for disposing subcode signals in subcode-signal blocks and data-signal information pieces in data-signal blocks, and for integrating subcode-signal block and data-signal block into complete television signal. Plurality of 2^m subcode-signal blocks are recorded on part of track allocated for subcode signal. Plurality of data-signal blocks are recorded on part of track allocated for data signal. There are facilities for generating time code signal and for disposing time code signals in definite subcode-signal blocks, facility for generating time code signals to be disposed in definite subcode-signal blocks on subcode-signal recording part, their ordinal numbers satisfying following formula: N(i) = [N(i-1)+1+2•p]mod2^m, where p is integer positive constant for which 0≤p≤2^(m-1)-1,a N(i) and N(i) is ordinal number of subcode synchronizing block on track numbered i whereon time code signal can be recorded; NCi) is integer number that may be 0 to 2^m - 1 and m is integer number higher than 0. EFFECT: reduced influence of noise and fall out of synchronism. 11 cl, 9 dwg
