The tape driver interface is documented in the file /usr/src/linux/drivers/scsi/README.st and on the st(4) man page (type man st). The file README.st also documents the different parameters and options of the driver together with the basic mechanisms used in the driver.
The tape driver is usually accessed via the mt command (see man mt). mtx is an associated program for controlling tape autoloaders (see mtx.sourceforge.net).
