ABSTRACT:
A magnetic tape recorder contains two tape buffer vacuum chambers disposed at opposed sides of a supply reel and a take-up reel situated therebelow. The open ends of the buffer chambers are both directed down and vacuum antechambers are disposed therebetween. Proceeding from the supply reel, magnetic tape is conducted through the buffer chamber and ante-chamber associated with the supply reel, over a magnetic head, over a drive capstan and through the antechamber and buffer chamber associated with the take-up reel to be taken up by the take-up reel. The magnetic tape recorder enables automatic threading of the magnetic tape and affords a compact structure adaptable even for very high tape speed operations.
