This is either incorrect, or system-dependent at best.  Sun's _Tutorial
on 1/4 Inch Tape Drives_ says, "The 150 Mbyte tape drive writes 18-track
tapes in the QIC-150 data format.  This tape drive uses 3M DC6150
(formerly DMDC600XTD) cartridges.  This drive can also read tapes
recorded in the QIC-120 data format on compatible cartridges, but does
not write data in this format."  

Reading between the lines in the same tutorial suggests that the 
QIC-120 format is 15 tracks, while QIC-150 is 18 tracks.
