ABSTRACT:
The present invention provides a pancake duplicator for sequentially recording multiple copies of program material on a pancake reel of blank recording tape. The apparatus and method disclosed facilitate and economize the commercial preparation of large numbers of video tape copies of program material. The apparatus includes a video tape drive unit capable of handling large reels or pancakes of raw, unrecorded video tape and transferring the tape past a video recording head to a takeup spool whereby many copies of a particular program are recorded on the pancake. In an alternate form, the recording functions are performed by a conventional recording device using an integrated tape drive capable of transporting tape from a pancake past the recording head to a takeup spool at the appropriate rate. In this alternate form, the apparatus includes an extension which engages the video cassette receiving opening in the conventional, industrial video tape recording machine and includes a plurality of guide rollers to present the tape for appropriate wrapping about the video tape head of the recorder to emulate a cassette. Independent drives in the apparatus are connected by appropriate circuitry to provide the necessary transfer of the tape during the recording process.
