Preventing cartridge tape stickiness

Can anyone provide any information about the best way to preserve cartridge tapes, such as DC300 tapes, so that parts of the tape don't stick together? Using new 3M DC300 tape several years ago, onto which I'd copied the source code to the S.6 version of the Accent operating system, the tape stuck together about two years later and was destroyed when I tried to read it. Not sure how to try to preserve the rest of the data, written with the Stut (the streaming tape utilitu software) software, that's still on the tape - any ideas? -- R. D.
