Single Reel Cartridge Media Helical Scan

A single reel tape cartridge can be adapted to a helical scan drive by first unreeling the leader block and tape onto a second reel before causing the tape to be drawn adjacent to the helical scan drive.

As shown in the figure, a single reel cartridge 10 is placed into the drive system. A threading arm 12 picks up a leader block 14 from the cartridge and loads the leader block 14 together with the web of tape 16 attached to the leader block into a take-up reel 18. The tape 16 is placed around handling pins 20 and between a capstan 22 and pinch roller 24. A rotator 26 includes rotating helical scan heads for reading and writing onto the tape 16. The handling pins 20 draw the tape 16 around the rotator 26 in the motion shown by dotted line 28. An erase head 30 can be provided for pre-erasing the tape 16.

A standard 1/2 inch tape cartridge can be adapted to a video recorder in the above manner. The threading arm 12 must be of a size to fit the opening of a video recorder and operate to sweep the tape out into the video tape cartridge opening and into contact with the handling pin 12 and capstan 22.
