Which headers? IIRC, TSM uses ANSI-standard tape labeling. So the VOL1 (tape label) is created when the tape is initialized and doesn't get updated/re-written from then on.
Each file should have a 'HDR1' label; this belongs to the file, so it will get written to the 'new' tape. From what I've read, TSM uses the file name field of the HDR1 label to store a bit-map pointer to the TSM database record that describes the file (the reason you can't recover the tape data without the TSM database).
