    Abstract: An improved self threading leader for a reel of recording tape which engages only itself as it is wrapped around the supply reel to maintain the reel's integrity and which engages a take-up hub to begin winding therearound when the reel is used with a tape transport unit of the type having a capstan to drive a supply reel and take-up hub by surface contact.

    Abstract: A system for automatically loading and tensioning a supply reel of magnetic recording which is contained in a tape cassette. The system is designed to be utilized with a tape transport mechanism of the type wherein the supply reel is driven by surface engagement of the outermost layer of tape on the reel with a capstan. A motor driven leadscrew mechanically engages the tape transport apparatus and functions as a means for sequencing its operation in a manner so that upon loading, the normally-closed cassette is opened and the tape pack is advanced by the transport apparatus into an operative position in which it is in contact with the capstan. Following the threading of the tape about the take-up reel, the leadscrew causes the transport apparatus to withdraw the supply tape pack from close contact with the capstan in order to allow slack to be removed therefrom through the action of a brake upon the supply reel. The supply tape pack is then once again brought back into its operative position in contact with the capstan.
