There are several types of tape drives available on the market. Most of them use the SCSI interface, all of which should be supported by Linux. Among the verified SCSI tape drives are the Sankyo CP150SE; Tandberg 3600; Wangtek 5525ES, 5150ES, and 5099EN with the PC36 adaptor. Other QIC-02 drives should be supported as well.
Drivers are currently under development for various other tape devices, such as Colorado drives which hang off of the floppy controller.
