The "pad" in analog tape parlance is a section of tape at the head of
a reel on which you can record the originating deck's head and EQ
signature using standard alignment tones (100 Hz, 1 and 15 KHz) for
use on another deck for alignment purposes. Blank time is left in the
"pad" to provide some tape for the engineer using a subsequent deck to
set up his record section to match (well, as much as possible)
azimuth, OPL and EQ with whatever the originating deck had. You
started seeing this in the late '60s, when production would jump from
studio to studio at the dawn of the "multi-track era." Prior to that,
in the dark ages of 3 track, you'd get an opening pad of three
alignment tones and that'd be it, but after copious multi-tracking in
different studios became the norm, the pad was enlarged to provide a
"scratch pad" area when the subsequent studio could play with record
parameters, also. Usually the "pad" is marked off from production
takes with a length of leader, although not always. Hopefully, the
sending engineer would scribble out his tone and pad times on the box,
but many didn't.
How to do it? Well, everyone seems to have their own way of doing
this, usually to the consternation of whoever gets the tape later. I
used to start with I KHz at 0 VU (usually 250 nWb/m back in my day)
for 60 seconds, 5 second break, then 100 Hz, break, then 15 Khz, then
a 3 minute record pad, then a leader break. I never got too many
complaints from others about that, although some always want a longer
record pad after the line-up tones, some would want more frequencies,
and some would want longer tones. Want to piss off someone down the
line? Give 'em the tones at 5 seconds each and a 30 second record
pad. The problem with doing that for the subsequent engineer is that
it always required a lot of rewinding to get through the line-up, and
unnecessary winding is a bad thing, period.
Usually, guys that would do this or wouldn't send you tones at all
would also be the ones who'd send you a really screwed up
tape...levels all over the map on takes, tracks pushed way into
saturation, lousy head line-up, you name it. I remember getting some
¼" two track "masters" from a certain funk singer who shall remain
nameless that were so screwed up, I sent them back with a note, "Try
again, do it right this time." He wanted them dubbed to ½" 2 trk,
because "that was mo' betta..." Durrrrrrrrr.... His "pad" was 1 KHz
at some ungodly hot level into saturation, and 100 Hz about 15 dB
down...and no azimuth tone at all. No sheet came with them, just some
indecipherable scribbling of song names on the box with no times. The
clown was running his own machines and obviously had not a clue as to
what he was doing. Also annoying were traces of coke dust all over
the reels. He didn't have many hits after that, either, as he had an
extended engagement at Hotel Greybar to attend to.
