Abstract
A rotary magnetic recording and reproducing apparatus includes a stationary cylinder formed on a lower portion of an outer peripheral surface thereof with a guide lead for guiding a lower edge of a magnetic tape and defining a tape running face on an upper portion of the outer peripheral surface thereof, a first bulge portion formed on an upper edge portion of the tape running face of the stationary cylinder on a tape leaving side of the upper edge portion of the tape running face and a second bulge portion which is smaller in height than the first bulge portion and formed on the upper edge portion of the tape running face on the tape leaving side thereof and in the vicinity of the first bulge portion on a tape incoming side of the first bulge portion. The first bulge portion serves to relax shock or vibration of a magnetic tape leaving the magnetic head and the second bulge portion serves to improve 'head-touch' of the magnetic tape.
