Back in the LTO-5 days, there was an issue with MAXELL tapes. See https://sourceforge.net/p/bacula/mailman/message/36060578/

The gist is that HP heads were harder material than IBM heads and if you used alot of out-of-spec abrasive MAXELL tapes, especially always fresh ones, then on IBM drives, the drives would suffer from premature "pole tip recession" and could no longer read or write any tape. HP drives seemed less affected.

To find out what manufacturer made the tape, you had to insert the tape into a drive and read the MAM chip over SCSI/SAS. With tapes basically everyone did alot of rebadging, so if you got a "HP" tape it could be anything from MAXELL to Sony to Fujifilm. "IBM" tapes were usually Fujifilm, i.e. good to use everywhere.
