TRACK SHEETS: are sheets used to keep a record of where the song is ( locate time on tape, or directory on HD) what tapes, client, which instrument is on which track, and various other notes.
RECALL SHEETS: are used to recall the settings of either the console or pieces of outboard gear. they are usually a graphic representation of the piece of gear. (or channel strip in the case of a console)
some studios actually take polaroids of the console so they can recall the settings by sight, not an approximated pencil line. but to me this sounds a little cheesy. of course with digital consoles ( or analog boards with "recall" programs) this is rendered obsolete.
