They're physical, they're just on disk. The s/w makes them "look" like tape.

Virtual Tape Systems provides an intelligently managed disk buffer between the mainframe and the tape storage system. Instead of writing directly to a physical drive, reads and writes are made to virtual drives. This enables high drive and cartridge utilization and should lower storage costs.
