Abstract
A helical scan magnetic tape recorder includes tape threading and guiding apparatus for threading magnetic tape from a two reel cassette about a rotary magnetic head scanner and for tensioning the tape during tape transport. The threading and guiding apparatus includes supply and take-up compliance elements which are mounted for movement between (1) cassette loading positions behind a tape span in a magnetic tape cassette; (2) tape vacuum loading positions in which the elements draw tape out of the cassette and partially contact it with the rotary head scanner; and (3) operating positions in which the elements draw tape around the respective supply and take-up capstans and tension the tape during tape transport past the rotary head scanner.
