The following is from a news file we keep on our system.
It isn't all the answers but it is a start.



QIC (Quarter Inch Cartridge) "buzz-numbers"
   Yes, there are more but this is what I know today.

QIC-02	The interface from the drive to a controller. This is the
	usual one for most AT buss controllers.  This has nothing
	to do with the format of the tape.
QIC-11	20MB, 4-track tape format.  Old, not really the thing these days
QIC-24	60MB, 9-track tape format.  Probably the most popular today.
QIC-40  40MB
QIC-80  80MB
QIC-120 125MB, 12-track tape format.  Never was in.
QIC-150 150MB, 18-track tape format.  This is what will be in next year.
QIC-320 320MB
QIC-??? 1G-byte, 30 tracks at 51,667 bpi (still under devel 5-89)

Tape drives:

Archive is the most popular manufacturer.  Their Viper series
is "in".  2150S is a QIC-150 drive with SCSI buss interface


The Tapes that these animals use:
	
DC-300	    Used for QIC-24
DC-600A	    Used for QIC-120
DC-600XTD   Used for QIC-150
DC-615	    New name for DC-600XTD
