Has anybody experimented with drying media in a vacuum chamber at room temperature? My abortive attempt to play with an old TK50 tape in a TZ30 drive was a disaster of sticking, oxide shedding, and manual unloading/respooling of a tape that the drive could no longer handle. I had not tried baking the tape. I do plan to make some sort of media baking setup when that project bubbles back to the top of the list. I wonder if pulling vacuum on a tape for a while might also have the desired effect? I have a bottle of cyclomethicone on order. I wonder if I might need to make some sort of reeling machine to apply it to tapes? The TK50 tapes are particularly resistant to manual manipulation. Maybe I could make a machine to allow me to unspool a TK50 tape while wiping on cyclomethicone and then re-spool it, perhaps by hacking up a drive mechanism. -- Mark J.
