ABSTRACT
Digital recording represents the first fundamental change in the industry’s system of duplicating the actual waveform, which is produced by a sound source, either by the mechanical method of cutting grooves in plastic or by the magnetic method of energized tape. Disk recordings may be classified into four types: instantaneous, pressings, direct to disk, and digital. In multitrack tape recording, the greater the number of tracks per tape width, or, more properly, the narrower each track, the lower the magnetic gain available from each track, and therefore the more gain needed from the track’s amplifiers. After recording is completed, any necessary tape editing takes place in an editing facility under the direction of an operator and tape editor. In monaural recording, also called full track and monophonic recording, the signal of one program channel is applied to virtually the full width of the tape.
