The term "Head Tones" refers to audio 
alignment tones, ususally in the form of a 
1Khz sine wave recorded at whatever 
reference level  the format that you are 
recording on. On a D1 tape, the 
reference level is -20 Dbu. The head tones 
are recorded at the start of the tape, 
usually accompanied by color bars if it is a 
video tape.
