3580 IBM Ultrium tapedrive &  3581 Tape Autoloader make sense but are modern DAT tapes.
I can find no referance to a 580 or 581 other than as the subchannel address of 580 for the active SID 
tape.

3420 used address	580 for tape emulated on disk. for that matter address 580 was used as the tape 
address in several places.

The RISC/6000 had a  7013 rev ... 58F, 58H, 580, ... that is 58 (Oh) not Zero 

Type 580 magnetic tape system with one transport ($19,700) ... on the PDP-8... not IBM :(

and 581 Tape Stations ... but that was on the RCA 501 

A picture, or more info ... please !!!!!!
