Data recorders and methods of recording digital data. |
摘要 |
<p>A predetermined amount of data to be recorded is treated as one frame, and data having a predetermined format is recorded for each frame. A first area for recording main data and a second area for recording sub data are formed in each frame. Plural types of data segmentation units each comprising a plurality of frames are set, and a first count signal (FMC) indicating the number of first units from a leading end of a recording medium (15) and other count signals (SSMC, RMC) indicating the numbers of other units from the leading end of the recording medium (15) to a trailing end of the first units are recorded in the second area of a frame constituting the unit including the trailing end, thus facilitating a high-speed search operation.</p> |
