9-track alignment (skew) tapes for R/W-head adjustment

Hi everybody, I had a look through my tapes and found one from Control Data being labeled "Total Service Tape". Does anybody know, if this tape also serves as an alignment tape? I couldn't find any information about that on the Net so far. I've been trying to resurrect one of my Fujitsu M2442AC tape drives. Even with heads cleaned,it fails the diagnostics when it comes to writing and reading a tape. It turned out that the drive head being held by a plastic plate was loose due to the plastic plate being broken. I tried to glue the plastic together, mounted the head back into its position, but the drive diagnostics still fails (error: F300 ). Azimuth-adjusting the head after remouting obviously needs an alignment tape. Having quite a collection of reel tape drives, I thought it would in any way make sense to have such a tape for head adjustment procedures, but they some to have become pretty rare these days (at least for 9-track 1/2" drives). Substituting these special tapes by any other tricks or ways seems not to come close to the alignment precision obtained wich alignment tapes. Thanks for any help in advance !
