Theory of Operation
The SuperLoader products are an integration of two separate
devices, a tape drive and a media changer. The media changer
consists of all the mechanics and electronics required to store and
move tape cartridges while the tape drive provides the read/write
functionality.
Each device has a separate interface for communication to the host.
The SCSI command set supported by the tape drive is documented
separately. The SCSI command set supported by the media
changer device is detailed in xxx.
The SuperLoader is fully compliant with the ANSI SCSI-2 standard
for tape drive and media changer devices and implements many
optional features.
The SuperLoader does not act as an initiator on the SCSI bus.
Therefore, it does not generate unsolicited interrupts to the bus,
initiate its own SCSI commands, or assert bus reset.
