Shouldn't this be possible for backward compatibility ?
Or was it between HP-41 and HP-67 ?

I don't have a primary source at hand, but I'm pretty sure that cards written by the HP-65 cannot be read by the 67.

The HP-41 card reader can read cards written by the HP-67 and -97, but that's as far as magnetic card compatibility goes.
