SUMMARY
=======
Compatibilty and tape capacity for QIC 117 standard tape backups depend on the
floppy disk drive controller, tape format, and the tape backup unit.
MORE INFORMATION
================
The controller requirements for floppy disk drive-based backups are as follows:
QIC117 Standard Supported Tape Formats
=============== ======================
QIC-40 Read/write QIC-40 tapes
QIC-80 Read QIC-40 tapes
Read/write QIC/80 tapes
Includes WIDE and TR-1 formatted tapes
QIC-3010 Read QIC-40/80 tapes
Read/write QIC-3010 tapes
Includes WIDE and TR-2 formatted tapes
if the drive will accept these
QIC-3020 Read QIC-40/80 tapes and QIC-3010 tapes
Read/write QIC-3020 tapes
Includes WIDE and TR-3 tapes

TITLE : Floppy Controller Requirements for QIC-117
QIC drives will not read tapes formatted with a later QIC Drive series format.
For example, QIC-3010 drives will not read QIC-3020-formatted tapes. QIC-40/80
drives will not read QIC-3010 or QIC-3020-formatted tapes.
The drive's functionality and capacity are limited to the lowest common
denominator of floppy disk drive controller speed, tape backup unit, or the tape
format itself. A QIC-3020 that requires a 1 Mbps controller for full
functionality essentially becomes a QIC-3010 series drive when placed on a 500
Kbps controller (and shares the same behavior and limitations as a 3010 Series
drive). Compatibility and limitations are summarized in the chart below:
