Abstract
This abstract describes an improvement in conventional vacuum column magnetic tape decks whereby the tape can be threaded directly across from one reel to the other after which it will automatically be threaded into the vacuum chambers, in sequential order. The first reel unwinds to load the first vacuum column and then the second reel unwinds to load the second column. The tape is held stationary over the capstan during the interval between the first entry of the tape into the first vacuum column until the tape has progressed within that column to a selected point after which time the tape is released. Before the tape is released there will be sufficient time available for the tape loop from the second reel to unwind and be locked into the second vacuum column.
