ABSTRACT:
A system for loading a predetermined length of magnetic tape paid out from a supply spool into a tape cassette in which the tension of the tape portion being paid out from the supply spool is at a different tension than the tension of the tape portion being taken up into the cassette. A pair of vacuum column tension members provide different tensions at the supply spool and at the take up spool, and a driving member interposes the two vacuum tension members for regulating tape movement between the same. During cassette loading, the take-up spool of the cassette is driven according to a driving signal which varies the movement of the tape at greatly varying speeds while the supply spool and interposing driving member are driven by signals formulated responsive to monitoring the length of the tape at the separate tension members.
