Travan, SLR, MLR and QIC tape media formats have been around for a number of years.  Tapes  eventually get replaced by faster, higher-capacity versions or completely different formats.  Based on the requests we receive there are companies all over still using their Travan, SLR/MLR or QIC tape drives.  Manufacturers have started raising prices on formats as the supply chain gets smaller; fewer and fewer firms are manufacturing these formats.  At least for now you can still find a 150MB QIC tape cartridge if you really need one.  The bigger capacity tapes like Tandberg SLR140 should be around for awhile until the laws of supply and demand take their course. 

We will continue to offer all the formats as long as they are available.  Eventually the higher capacity formats like LTO-4 (1.6TB compressed capacity!) will be the EOL products we are starting to see now is the QIC formats.

I am more than happy to track down any older formats you might need...call us at 866-926-1669; we can often locate product that might not be listed on our site.
