Digital recording
Unlike analog recording, digital recording reproduces discrete numbers, and coding techniques can be used to ensure that the occurrence of bit errors is negligible. When this is done, digital recording has no sound quality because the presence of the recorder makes no difference to the data. This is advantageous because more effort can then be applied to the design of converters which do affect the quality.
10.1 Introduction
In digital tape recording the transport may resemble the analog transports shown in Chapter 9 except that the tape tracks are narrower. The difference is in the way the head signals are processed. Figure 10.1 shows the block diagram of a machine of this type. Analog inputs are converted to the ...
