Time Code in Sub Data Area of R-DAT
Control functions of tape locating and synchronizing with other equipment are indispensable when using the R-DAT format in professional applications. The time code characteristic of R-DAT is unsuitable for this purpose and it is preferable to use the SMPTE/EBU time code which is more popular today. SMPTE/EBU time code, however, cannot be recorded directly due to the difference in frame cycle. In view of this situation, we have devised a format for recording in the sub data area, which allows use of the SMPTE/EBU time code in the conventional manner and also reading out under high tape speeds. We have developed a product incorporating a control system which fulfills the above objective. In the following, we wish to propose application of this new format.
