If you started your career pulling honest-to-Gawd reel-to-reeal multitrack tapes, and taking notes on every take on track sheets with a good old #2 lead pencil, you just never stop. I still use track sheets even though I'm tapeless now. Always will.
Track sheets used to be organized on a take-by-take basis using tape counter readings when I first started out, back in the days before timecode hardware was affordable by mere mortal man. I just write 'em up with the disk directory index (the "program number") these days. Used to be you'd note the tape counter offset reading, using the leader splice as 0, so you could spool right to it.
I don't care that I can take notes in Cubase. Takes too long. Got that good ol' pencil right there, and a clipboard with a space to put it all down, and I've learned to write without unfocusing my ears. I just flat can't do that typing...
It's still fun to pull an old reel off the shelf from my old room, open up the box, find the track sheets inside, and try to remember the day. Even though it's arguably bad form, I always stored the sheets right in the box with the reel. That was because my collaborators never could get used to labeling the boxes, or splicing on head and tail leaders and labeling the tape itself. So after they'd track, I'd find a bunch of blank tape boxes stacked all over the control room, with no heads or tails or markings at all, and have no freakin' _idea_ what it was, whether it was heads- or tails-out, or even if it had been used... What a timewaster.
I ought to scan my current track sheet and post it. It's based on my old one... At the bottom, it has a quote from the 1980 National Lampoon parody of the US Census form: "Fill out this form completely, or we'll fuck with your head until you bleed out the ears."
It worked pretty well getting my collaborators into line, most of the time, sort of. Maybe 50%, anyway. That, and my official policy of "If it's in a blank box with no track sheet and no leaders, it's gonna get treated as if it's blank tape, dammit!" And that's why I'm strictly a solo act in my new room, when it comes to engineering.
I still keep a pile of Sharpies and grease pencils by the board, even though there's nothing to label anymore... Just like the smell of 'em, I guess. I just wish that I could figure out how to store hard disk drives tails-out... (;-) Let's hear it for the dinosaurs!
