BS EN 61120-2 discusses a digital audio tape recorder reel-to-reel system, using 6.3 mm magnetic tape, for professional use with a focus on format A. BS EN 61120-2 is the second part of the multi-series on digital audio tape recorder reel-to-reel system that provides a method that is first defined to convert binary data sequence of each of the 8 main digital tracks for recording on the magnetic tape. The second item described is the definition of the synchronization pattern in recording code. The converted code is given by NRZI.
The 2/4 M system is defined by dividing a binary data sequence into two-bit data segments and converting these into four-cell codes using the data of the four bits preceding and the four bits succeeding the two-bit data segment.
BS EN 61120-2 on digital audio tape recorder reel-to-reel system is useful for:
BS EN 61120-2 discusses main track recording, sub-track recording, and control word.
BS EN 61120-2 will help you to understand digital audio reel-to-reel recording and reproducing systems.
BS EN 61120-2 gives guidance to convert the binary data sequence of each of the 8 main digital tracks for recording on the magnetic tape. The second item described is the definition of the synchronization pattern in recording code.
