Several months ago I posted a request for info on cartridge
tape formats. I have heard the names of some of them
(QIC 24 seems to be the name of a standard format, for example)
but have been unable to find any info on what the formats
really are, which vendors use which formats, etc.
So, if YOU have ANY information (what does QIC stand for?
what format do your company's tape drives use? ...) PLEASE
send it my way, and I will summarize to the net.

QIC stands for "Quarter Inch Committee". I am not sure whether QIC is an Accredited Standards Committee or not. I refer you to an article by W.L. Rosh in PC Magazine, 6/23/87 v.6 # 12. I extract the following from my notes: QIC40: 20 tracks over the width of the tape, each containing 2Mbyte of data. Each track consists of 68 segments of 29 sectors, each containing 1024bytes. FAT lists the bad sectors. Recording done using modified FM - "double density" at 10Kbits/inch. Drives run at 25 or 50 ips. QIC100: 12-24 tracks. has less stringent compliance requirements than QIC40. Manufacturers: QIC40: Archive Corp. Costa Mesa CA 714/641-0279 Mountain Computer Scotts Valley CA 800/458-0300 QIC100: Advanced Digital Information Corp. Redmond WA 800/336-1233 Tallgrass Technologies Overland Park KS 800/228-3475 I hope this helps. --Martin Weiss
