If you have a tape with text like the following in the first 32 bytes: 
   STORE/RESTORE LABEL-HP/3000.VIIB
then you have a backup tape ("Classic STORE tape") from an HP 3000, running the MPE V (or older) operating system.

Allegro Consultants, Inc., offers data recovery for Classic STORE tapes, including DDS data recovery, DAT data recovery, and DLT data recovery, as well as other forms of tape media.

Here's a dump of the first record of a typical Classic STORE tape.
Note that a few of the fields will change from tape to tape, but that the first 32 bytes are constant: 

   EOF
